Typical properties for CHO-SEAL 1310 and 1273 materi-al are shown on pages 33 and 32respectively.High Shielding PerformanceCHO-SEAL 1310 material provides more than 80 dB of shielding effectiv-ness from 100 MHz to 10 GHz, while CHO-SEAL 1273 material provides more than 100 dB.Low Volume ResistivityBoth materials have exceptionally low volume resistivity, which makes them well suited for grounding appli-cations in which a flexible electrical contact is needed.Low Compression GasketSpacer gaskets are typicallydesigned to function under low deflec-tion forces. Chomerics uses design tools such as Finite Element Analysis (FEA) to accurately predict compres-sion-deflection behavior of various cross section options. Refer to page16.LCP Plastic SpacerLiquid crystal polymer (LCP)spacers, including those made with Vectra A130 material, provide aCHO-SEAL ®1310 or 1273Conductive ElastomersWith EMI spacer gaskets, shielding and grounding are provided by Chomerics’CHO-SEAL 1310 and 1273 conductive elastomers, specifi-cally formulated for custom shape molded parts. They provide excellent shielding and isolation against electro-magnetic interference (EMI), or act as a low impedance ground path between PCB traces and shielding media. Physically tough, these elas-tomers minimize the risk of gasket damage, in contrast to thin-walled extrusions or unsupported molded gaskets.Silicone-based CHO-SEAL 1310and 1273 materials offer excellent resistance to compression set over a wide temperature range, resulting in years of continuous service. CHO-SEAL 1310 material is filled with silver-plated-glass particles, while 1273 utilizes silver-plated-copper filler to provide higher levels of EMI shielding effectiveness.EMI Spacer GasketsThe unique design of Chomerics’EMI spacer gaskets features a thin plastic retainer frame onto which a conductive elastomer is molded. The elastomer can be located inside or outside the retainer frame, as well as on its top and bottom surface. EMI spacer gaskets provide a newapproach to designing EMI gaskets into handheld electronics such as dig-ital cellular phones. Board-to-board spacing is custom designed to fit broad application needs. Customized cross sections and spacer shapes allow for very low closure forcerequirements and a perfect fit in any design or device.Robotic InstallationSpacer gaskets can be installed quickly by robotic application. Integral locater pins in the plastic spacer help ensure accuratepositioning in both manual and pick-and-place assembly. Benefits include faster assembly and lower labor costs.The integrated conductive elastomer/plastic spacer gasket is a low cost,easily installed system for providing EMI shielding and grounding in small electronic enclosures.Figure 1Single Piece EMI Gasket/Locator PinsCHO-SEAL 1310 or 1273 Conductive Elastomer (Inside)Plastic Spacer Around Outsideor InsideApplications for EMI Spacer GasketsThe spacer gasket concept is especially suited to digital and dual board telephone handsets or other handheld electronic devices. It provides a low impedance path between peripheral ground traces on printed circuit boards and components such as:•the conductive coating on a plastic housing•another printed circuit board •the keypad assemblyTypical applications for EMI spacer gaskets include:•Digital cellular, handyphone and personal communications services (PCS) handsets •PCMCIA cards•Global Positioning Systems (GPS)•Radio receivers•Other handheld electronics, e.g.,personal digital assistants (PDAs)•Replacements for metal EMI shield-ing “fences” on printedcircuit boards in wireless tele-communications devicesstable platform for direct, highprecision molding of conductive elas-tomers. The Vectra A130 material described in Table 1 has excellent heat deflection temperature character-istics (489°F, 254°C). For weight con-siderations, the LCP has aspecific gravity of only 1.61.

Supertex inc.AN-H59Application NoteApplication CircuitHigh Voltage DC/DC Converter forSupertex Ultrasound Transmitter DemoboardsBy Afshaneh Brown, Applications Engineer,and Jimes Lei, Applications ManagerIntroductionThe Supertex AN-H59DB1 demoboard is a high voltage DC/DC converter. It can provide up to +90V voltage supply for V PP and -90V for V NN . It also provides +8.0 to +10V voltage supply for V DD , floating power supplies of V NN +8.0 to V NN +10V for V NF and V PP -8.0 to V PP -10V for V PF . The input supply voltage is 12V.The AN-H59DB1 circuitry consists of two high voltage PWM Current-Mode controllers, a DC/DC transformer driver, and three low dropout regulators. The Supertex AN-H59DB1 uses a high-voltage, current mode, PWM controller boost topology to generate +15 to +90V and a high-voltage current mode PWM controller buck-boost topology to generate -15 to -90V power supply voltage for Supertex HV738DB1 and HV748DB1 ultrasound transmitter demoboards.Each of the transmitter demoboards has slightly different operating voltages as summarized below.To accommodate all three demoboards, the AN-H59DB1 demoboard has adjustable V PP , V NN , V DD , V PF and V NF . The purpose of the AN-H59DB1 is to aid in the evaluation of the three transmitter demoboards. The intention of this application note is to provide a general circuit description on how each of the output voltages is generated.The VSUB pin on the HV738DB1 and HV748DB1 can either be connected to the most positive supply voltage on the demoboard, or can be left floating.To power up the AN-H59DB1, ensure that the 3.3V power supply will be powered up first, and then the 12V power supply. The sequences on the HV738DB1 and HV748DB1 took into consideration using the protection diodes on each power line.The circuit is shown in Figure 6, the component placement in Figure 5, and the bill of materials is at the end of thisapplication note.PP The circuit in Figure 1 shows U5, the Supertex high volt -age current mode PWM controller, being used to generate the high voltage power supply for V PP . The maximum output power for V PP was set for 10mA at 90V, which is 900mW. With an input voltage of 12V, a converter frequency of 110 kHz with a 100µH inductor was chosen to provide the de -sired output power.The converter frequency is set by an external resistor, R20, across OSC IN and OSC OUT pins of U5. A 154kΩ resistor will set the frequency to about 110 kHz. R24 is the current sense resistor. 2.2Ω was used to set the maximum peak current limit to about 450mA. An RC filter, R23 and C15, is added between the current sense resistor and the current sense terminal pin 3 of U5. This reduces the leading edge spike on R24 from entering the current sense pin.Inductor L1 is being charged from the 12V input by M3. When M3 turns off, the energy in L1 is discharged into C16, which is the V PP output through D8. The V PP voltage is di-vided down by feedback resistors R25, R26, and R27. The wiper of R26 is connected to pin 14 of U5. The overall con -verter will regulate the voltage on pin 14 to 4.0V. Different V PP output voltages can be obtained by adjusting R26.When the wiper for R26 is set to the top, V PP can be calcu-lated as:where V FB is 4.0VWhen the wiper for R26 is set to the bottom, V PP can be calculated as:By adjusting potentiometer R26, V PP meets the adjustable target range of 15 to parator U6 will turn on LED D7 when the V PP output is out of regulation due to excessive load. During initial power up, C16 will be at 0V. D7 is therefore expected to be on until C16 is charged to the desired regulation voltage.Figure 1: Adjustable V PP Power SupplyV PPGNDV PP = 4.0V x ( 232k + 100k + 14.3k )= 12.1V 100k + 14.3k V PP= V FBx ( R25 + R26 + R27 )R26 + R27V PP = 4.0V x ( 232k + 100k + 14.3k )= 96.9V 14.3kV PP = V FBx ( R25 + R26 + R27 )R27NN The circuit in Figure 2 shows U7, the Supertex high voltage current mode PWM controller, being used to generate the high voltage power supply for V NN . The function of U7 is very similar to what was described in the V PP circuit description for U5. However, in this circuit a negative voltage is gener -ated from a positive input voltage source, therefore requir-ing a buck-boost topology. The maximum output power for V NN was set for -10mA at -90V which is 900mW. With an input voltage of 12V, a converter frequency of 110 kHz with a 100µH inductor was chosen to provide the desired output power.Inductor L2 is being charged from the 12V input by the par-allel combination of M6 and M7. When M6 and M7 turn off, the energy in L2 is discharged into C23, which is the V NNoutput through D10. M6 and M7 are high voltage P-channel MOSFETs. U7 is designed to drive a high voltage N-chan -nel MOSFET. The drive output for U7 therefore needs to be inverted. This is accomplished by M4 and M5.The feedback voltage that U7 detects on pin 14 is +4.0V. The V NN that needs to be sensed is a negative voltage. A cir-cuit is needed to make sure the feedback voltage is positive. This is consists of Q4, Q5, R33, R34, R35, R37, and R38. Q4 becomes a constant current sink set by the V NN voltageand R35. The same current will be flowing through R33 and R34.The voltage on the base of Q5 will be V IN minus the voltage drop across the sum of R33 and R34. By varying R34, the base voltage on Q5 will change. Q5 becomes a constant current source with a value set by its base voltage and R37. The current source of Q5 is going into R38, which creates a positive voltage that is now proportional to the magnitude of V NN .where V BE = 0.6V, V FB = 4.0V.When R34 is set to 100k, V NN is calculated to be:= -4.0VWhen R34 is set to 0k, V NN is calculated to be:= -97.4V By adjusting potentiometer R34, V NN meets the adjustable target range of -15 to parator U8 will turn on LED D9 when the V NN output isout of regulation due to excessive load. During initial power up, C23 will be at 0V. D9 is therefore expected to be on until C23 is charged to the desired regulation voltage.Figure 2: Adjustable V NN Power SupplyVNN-15V to -90V GNDV NN = V BE - ( R35 ) x (V BE + V FB x R37 ), R33 + R34 R38V NN = 0.6V - ( 273k) x (0.6V + 4.0V x 14.7k ) 4.99k + 100k 40.2k V NN = 0.6V - ( 273k ) x (0.6V + 4.0V x 14.7k )4.99k + 0k 40.2kVPF and VNF Circuit DescriptionThe three transmitter demoboards require two floating low voltage supplies, V PF and V NF . The floating supplies need to be adjustable to accommodate the different operating re-quirements for the three different boards. The V PF is 8.0 to 10V below the high voltage V PP positive supply. The V NF is 8.0 to 10V above the high voltage V NN negative supply. The two floating supplies are generated by using two isolated transformers, T1 and T2, and an isolated transformer driver, U1, as shown in Figure 4. Both outputs utilize adjustable low dropout linear regulators, U2 and U3, as shown in Figure 3. U2 and U3 are both Linear Technology LT1521, which has a reference voltage of 3.75V on the ADJ pin. For V PF , resistors R6, R7, and R8 set the output V PF voltage. R7 is a potentiom -eter for adjusting V PF . V PF can be calculated with the following equation:When R7 is set to 20kΩ, V PF becomes:When R7 is set to 0Ω, V PF becomes:Please note that the OUT pin on U2 is referenced to V PP , thereby setting V PF to be 8.0 to 10V below V PP . V NF can also be calculated in a similar manner using resistors R12, R13, and R14. Please note that the GND pin on U3 is referenced to V NN thereby setting V NF to be 8.0 to 10V above V NN .LED indicators, D5 and D11, start to turn on when the input current to U2 and U3 reaches an arbitrary value of 40mA. This is set by Q1 and R3 for V PF and Q2 and R9 for V NF . The input current can be calculated with the following equation: Input current = V EB = 0.5V = 41.3mA R 12.1Ω50mA current limits are added to protect against output shorts. The current limiter is consists of a depletion-mode MOSFET and a series source resistor. The resistor sets the current limit and can be estimated with the following equa -tion:R SERIES = V TH x ( √I LIM / I DSS - 1) where, I LIMV TH = pinch-off voltage for M1 and M2: -2.5V I LIM = desired current limit: 50mAI DSS = saturation current for M1 and M2: 1.1A R SERIES = 39.3Ω. A 40.2Ω resistor was used.Figure 3: Adjustable V PF and V NF Power SupplyV VNFVFPV PF = 3.75V x ( 45.3k + 20k + 24.9k )= 7.53V 20k + 24.9kV PF = 3.75V x ( 45.3k + 0k + 24.9k )= 10.6V 0 +24.9kV PF= V ADJx ( R6 + R7 + R8 )R7 + R8V DD Circuit DescriptionThe V DD output voltage utilizes an adjustable low dropout lin -ear regulator, U4 LT1521, as shown in Figure 4. The desiredadjustable output voltage range is 8.0 to 10V to accommo-date the different operating V DD voltages for the three differ-ent transmitter demoboards.The LT1521 has a reference voltage of 3.75V on the adj pin. Resistors R17, R18, and R19 set the output V DD voltage. R18 is a potentiometer for adjusting V DD . V DD can be calcu-lated with the following equation:When R18 is set to 20kΩ, V DD becomes:When R18 is set to 0Ω, V DD becomes:An LED indicator, D6, is included in case of excessive input,I IN, current. D6 is starts to turn on when the input currentreaches an arbitrary value of 20mA. This is set by Q3 and R15. When the emitter-base junction of Q3 is forward biased (0.5V), Q3 will start to turn on, thereby forward biasing D6.The I IN value to turn D6 on can be calculated with the follow -ing equation: I IN = V EB = 0.5V= 20.6mAR1524.3Ω 3.3V Input TerminalThe AN-H59DB1 has a 3.3V input terminal that is directly connected to the output terminal, V CC . There is no circuitry on this board that uses the 3.3V supply. It is only there as a convenient connection to the 8-pin header. V CC is the logic supply voltage for HV738DB1 and HV748DB1 and can oper-ate from 1.2 to 5V. However, most users will operate V CC at either 3.0 or 3.3V.Input and Output PowerThe output voltages from the AH-H59DB1 are all generated from the 12V input line. With no load on the outputs, the measured input current was about 70mA. This input current can vary from board to board due to variations in the isolated transformer.The maximum output power is:P OUT(MAX) = P VPP(MAX) + P VNN(MAX) + P VPF(MAX) + P VNF(MAX) + P VDD(MAX)P OUT(MAX) = 0.9W + 0.9W + 0.4W + 0.4W + 0.2W P OUT(MAX) = 2.8WUnder this condition, the 12V input current was measured to be 340mA. Input power is therefore 4.08W. This gives an approximate overall efficiency of 69% at full load.Figure 4: Adjustable V DD Power SupplyV IN = 12VVDD+8.0 to 10V GNDV DD = 3.75V x ( 45.3k + 20k + 24.9k )= 7.53V20k + 24.9kV DD = 3.75V x ( 45.3k + 0k + 24.9k )= 10.6V 0 + 24.9k V DD = V ADJ x ( R17 + R18 + R19 )R18 + R19VPF and VNF Output CurrentThe AN-H59DB1 can supply more than 40mA of current for the V PF and V NF outputs. The I NF and I PF input currents for the HV738 or the HV748 can be found in their respective datasheet but are summarized below:This is for continuous 5.0 MHz operation. For ultrasound, thehigh voltage transmitter is operating at very low duty cycles; 1% or lower. At a 1% duty cycle, the average current is ex -pected to be a 100 times lower. The 40mA output current ca -pability on the AN-H59DB1 is more than sufficient to power up the HV738 or the HV748.ConclusionThe main purpose of AN-H59DB1 power supply demoboard is to help the evaluation of the Supertex HV738DB1 and HV748DB1 demoboards by reducing the number of power supplies needed. The AN-H59DB1 was designed to operate from a single 12V input which should be commonly available in any engineering laboratory.The five on-board LEDs allow the user to quickly determine whether there is an overload condition on each of the supplylines. The five potentiometers allow the user to easily adjust each supply to meet their particular needs.Figure 5: AN-H59 Component PlacementFigure 6: AN-H59 Circuit SchematicVPPVPFVNFSupertex inc. does not recommend the use of its products in life support applications, and will not knowingly sell them for use in such applications unless it receives an adequate “product liability indemnification insurance agreement.” Supertex inc. does not assume responsibility for use of devices described, and limits its liability to the replacement of the devices determined defective due to workmanship.

Primary side control circuit common and reference point.TOPSwitch-HX Family Functional DescriptionLike TOPSwitch-GX, TOPSwitch-HX is an integrated switched mode power supply chip that converts a current at the control input to a duty cycle at the open drain output of a high voltage power MOSFET. During normal operation the duty cycle of the power MOSFET decreases linearly with increasing CONTROL pin current as shown in Figure 9.In addition to the three terminal TOPSwitch features, such as the high voltage start-up, the cycle-by-cycle current limiting, loop compensation circuitry, auto-restart and thermalshutdown, the TOPSwitch-HX incorporates many additional functions that reduce system cost, increase power supply performance and design fl exibility. A patented high voltageCMOS technology allows both the high-voltage power MOSFET and all the low voltage control circuitry to be cost effectively integrated onto a single monolithic chip.Three terminals, FREQUENCY, VOLTAGE-MONITOR, andEXTERNAL CURRENT LIMIT (available in Y and E/L packages),two terminals, VOLTAGE-MONITOR and EXTERNAL CURRENT LIMIT (available in M package) or one terminal MULTI-FUNCTION (available in P and G package) have been used to implement some of the new functions. These terminals can be connected to the SOURCE pin to operate the TOPSwitch-HX in aTOPSwitch-like three terminal mode. However, even in this three terminal mode, the TOPSwitch-HX offers many transparent features that do not require any external components:A fully integrated 17 ms soft-start significantly reduces or eliminates output overshoot in most applications by sweeping both current limit and frequency from low to high to limit the peak currents and voltages during start-up.A maximum duty cycle (DC MAX ) of 78% allows smaller inputstorage capacitor, lower input voltage requirement and/or higher power capability.Multi-mode operation optimizes and improves the powersupply effi ciency over the entire load range while maintaining good cross regulation in multi-output supplies.1.2.3.Figure 9.

In this mode, the value of the resistor determines the OV/UV thresholds and the DC MAX is reduced linearly with a dual slope to improve line ripple rejection. In addition, it also provides another threshold to implement the latched and hysteretic output overvoltage protection (OVP). The pin can also be used as a remote ON/OFF using the I UV threshold.The EXTERNAL CURRENT LIMIT (X) pin can be used to reduce the current limit externally to a value close to the operating peak current, by connecting the pin to SOURCE through a resistor. This pin can also be used as a remote ON/OFF input.For the P and G package the VOLTAGE-MONITOR andEXTERNAL CURRENT LIMIT pin functions are combined on one MULTI-FUNCTION (M) pin. However, some of the functions become mutually exclusive.The FREQUENCY (F) pin in the TOP254-258 Y and E/L packages set the switching frequency in the full frequency PWM mode to the default value of 132 kHz when connected to SOURCE pin. A half frequency option of 66 kHz can be chosen by connecting this pin to the CONTROL pin instead. Leaving this pin open is not recommended. In the P , G and M packages and the TOP259-261 Y packages, the frequency is set internally at 66 kHz in the full frequency PWM mode.CONTROL (C) Pin OperationThe CONTROL pin is a low impedance node that is capable of receiving a combined supply and feedback current. During normal operation, a shunt regulator is used to separate thefeedback signal from the supply current. CONTROL pin voltage V C is the supply voltage for the control circuitry including the MOSFET gate driver. An external bypass capacitor closely connected between the CONTROL and SOURCE pins is required to supply the instantaneous gate drive current. The total amount of capacitance connected to this pin also sets the auto-restart timing as well as control loop compensation.When rectifi ed DC high voltage is applied to the DRAIN pin during start-up, the MOSFET is initially off, and the CONTROL pin capacitor is charged through a switched high voltage4.5.6.7.8.9.current source connected internally between the DRAIN and CONTROL pins. When the CONTROL pin voltage V C reaches approximately 5.8 V, the control circuitry is activated and the soft-start begins. The soft-start circuit gradually increases the drain peak current and switching frequency from a low starting value to the maximum drain peak current at the full frequency over approximately 17 ms. If no external feedback/supplycurrent is fed into the CONTROL pin by the end of the soft-start, the high voltage current source is turned off and the CONTROL pin will start discharging in response to the supply current drawn by the control circuitry. If the power supply is designed properly, and no fault condition such as open loop or shorted output exists, the feedback loop will close, providing external CONTROL pin current, before the CONTROL pin voltage has had a chance to discharge to the lower threshold voltage of approximately 4.8 V (internal supply undervoltage lockout threshold). When the externally fed current charges theCONTROL pin to the shunt regulator voltage of 5.8 V, current in excess of the consumption of the chip is shunted to SOURCE through an NMOS current mirror as shown in Figure 3. The output current of that NMOS current mirror controls the duty cycle of the power MOSFET to provide closed loop regulation. The shunt regulator has a fi nite low output impedance Z C that sets the gain of the error amplifi er when used in a primary feedback confi guration. The dynamic impedance Z C of the CONTROL pin together with the external CONTROL pin capacitance sets the dominant pole for the control loop.When a fault condition such as an open loop or shorted output prevents the fl ow of an external current into the CONTROL pin, the capacitor on the CONTROL pin discharges towards 4.8 V. At 4.8 V, auto-restart is activated, which turns the output MOSFET off and puts the control circuitry in a low current standby mode. The high-voltage current source turns on and charges the external capacitance again. A hysteretic internal supply undervoltage comparator keeps V C within a window of typically 4.8 V to 5.8 V by turning the high-voltage current source on and off as shown in Figure 11. The auto-restart circuit has a divide-by-sixteen counter, which prevents the output MOSFET from turning on again until sixteen discharge/charge cycles have elapsed. This is accomplished by enabling the output MOSFET only when the divide-by-sixteen counter reaches the full count (S15). The counter effectively limitsTOPSwitch-HX power dissipation by reducing the auto-restart duty cycle to typically 2%. Auto-restart mode continues until output voltage regulation is again achieved through closure of the feedback loop.Oscillator and Switching FrequencyThe internal oscillator linearly charges and discharges an internal capacitance between two voltage levels to create atriangular waveform for the timing of the pulse width modulator. This oscillator sets the pulse width modulator/current limit latch at the beginning of each cycle.The nominal full switching frequency of 132 kHz was chosen to minimize transformer size while keeping the fundamental EMI frequency below 150 kHz. The FREQUENCY pin (available only in TOP254-258 Y and E, L packages), when shorted to the CONTROL pin, lowers the full switching frequency to 66 kHzRev. F 01/09Figure 10. Switching Frequency Jitter (Idealized V DRAIN Waveforms).(half frequency), which may be preferable in some cases such as noise sensitive video applications or a high effi ciency standby mode. Otherwise, the FREQUENCY pin should be connected to the SOURCE pin for the default 132 kHz. In the M, P and G packages and the TOP259-261 Y package option, the full frequency PWM mode is set at 66 kHz, for higher effi ciency and increased output power in all applications.To further reduce the EMI level, the switching frequency in the full frequency PWM mode is jittered (frequency modulated) by approximately ±2.5 kHz for 66 kHz operation or ±5 kHz for 132 kHz operation at a 250 Hz (typical) rate as shown in Figure 10. The jitter is turned off gradually as the system is entering the variable frequency mode with a fi xed peak drain current.Pulse Width ModulatorThe pulse width modulator implements multi-mode control by driving the output MOSFET with a duty cycle inversely proportional to the current into the CONTROL pin that is in excess of the internal supply current of the chip (see Figure 9). The feedback error signal, in the form of the excess current, is fi ltered by an RC network with a typical corner frequency of 7 kHz to reduce the effect of switching noise in the chip supply current generated by the MOSFET gate driver.To optimize power supply effi ciency, four different control modes are implemented. At maximum load, the modulator operates in full frequency PWM mode; as load decreases, the modulator automatically transitions, fi rst to variable frequency PWM mode, then to low frequency PWM mode. At light load, the control operation switches from PWM control to multi-cycle-modulation control, and the modulator operates in multi-cycle-modulation mode. Although different modes operate differently to make transitions between modes smooth, the simple relationship between duty cycle and excess CONTROL pin current shown in Figure 9 is maintained through all three PWM modes. Please see the following sections for the details of the operation of each mode and the transitions between modes.Full Frequency PWM mode: The PWM modulator enters full frequency PWM mode when the CONTROL pin current (I C ) reaches I B . In this mode, the average switching frequency is kept constant at f OSC (66 kHz for P , G and M packages and TOP259-261 Y, pin selectable 132 kHz or 66 kHz for Y and E/Lpackages). Duty cycle is reduced from DC MAX through the reduction of the on-time when I C is increased beyond I B . This operation is identical to the PWM control of all other TOPSwitch families. TOPSwitch-HX only operates in this mode if the cycle-by-cycle peak drain current stays above k PS(UPPER)*I LIMIT (set), where k PS(UPPER) is 55% (typical) and I LIMIT (set) is the current limit externally set via the X or M pin.Variable Frequency PWM mode: When peak drain current is lowered to k PS(UPPER)* I LIMIT (set) as a result of power supply load reduction, the PWM modulator initiates the transition to variable frequency PWM mode, and gradually turns off frequency jitter. In this mode, peak drain current is held constant at k PS(UPPER)* I LIMIT (set) while switching frequency drops from the initial full frequency of f OSC (132 kHz or 66 kHz) towards the minimum frequency of f MCM(MIN) (30 kHz typical). Duty cycle reduction is accomplished by extending the off-time.Low Frequency PWM mode: When switching frequencyreaches f MCM(MIN) (30 kHz typical), the PWM modulator starts to transition to low frequency mode. In this mode, switchingfrequency is held constant at f MCM(MIN) and duty cycle is reduced, similar to the full frequency PWM mode, through the reduction of the on-time. Peak drain current decreases from the initial value of k PS(UPPER)* I LIMIT (set) towards the minimum value ofk PS(LOWER)*I LIMIT (set), where k PS(LOWER) is 25% (typical) and I LIMIT (set) is the current limit externally set via the X or M pin.Multi-Cycle-Modulation mode: When peak drain current is lowered to k PS(LOWER)*I LIMIT (set), the modulator transitions to multi-cycle-modulation mode. In this mode, at each turn-on, the modulator enables output switching for a period of T MCM(MIN) at the switching frequency of f MCM(MIN) (4 or 5 consecutive pulses at 30 kHz) with the peak drain current of k PS(LOWER)*I LIMIT (set), and stays off until the CONTROL pin current falls below I C(OFF). This mode of operation not only keeps peak drain current low but also minimizes harmonic frequencies between 6 kHz and30 kHz. By avoiding transformer resonant frequency this way, all potential transformer audible noises are greatly supressed.Maximum Duty CycleThe maximum duty cycle, DC MAX , is set at a default maximum value of 78% (typical). However, by connecting the VOLTAGE-MONITOR or MULTI-FUNCTION pin (depending on the package) to the rectifi ed DC high voltage bus through a resistor with appropriate value (4 M Ω typical), the maximum duty cycle can be made to decrease from 78% to 40% (typical) when input line voltage increases from 88 V to 380 V, with dual gain slopes.Error Amplifi erThe shunt regulator can also perform the function of an error amplifi er in primary side feedback applications. The shunt regulator voltage is accurately derived from a temperature-compensated bandgap reference. The CONTROL pin dynamic impedance Z C sets the gain of the error amplifi er. TheCONTROL pin clamps external circuit signals to the V C voltage level. The CONTROL pin current in excess of the supply current is separated by the shunt regulator and becomes the feedback current I fb for the pulse width modulator.Rev. F 01/09On-Chip Current Limit with External ProgrammabilityThe cycle-by-cycle peak drain current limit circuit uses the output MOSFET ON-resistance as a sense resistor. A current limit comparator compares the output MOSFET on-state drain to source voltage V DS(ON) with a threshold voltage. High drain current causes V DS(ON) to exceed the threshold voltage and turns the output MOSFET off until the start of the next clock cycle. The current limit comparator threshold voltage is temperature compensated to minimize the variation of the current limit due to temperature related changes in R DS(ON) of the output MOSFET. The default current limit of TOPSwitch-HX is preset internally. However, with a resistor connected between EXTERNAL CURRENT LIMIT (X) pin (Y, E/L and M packages) or MULTI-FUNCTION (M) pin (P and G package) and SOURCE pin (for TOP259-261 Y, the X pin is connected to the SIGNAL GROUND (G) pin), current limit can be programmed externally to a lower level between 30% and 100% of the default current limit. By setting current limit low, a larger TOPSwitch-HX than necessary for the power required can be used to take advantage of the lower R DS(ON) for higher effi ciency/smaller heat sinkingrequirements. TOPSwitch-HX current limit reduction initial tolerance through the X pin (or M pin) has been improved signifi cantly compare with previous TOPSwitch-GX. With a second resistor connected between the EXTERNAL CURRENT LIMIT (X) pin (Y, E/L and M packages) or MULTI-FUNCTION (M) pin (P and G package) and the rectifi ed DC high voltage bus, the current limit is reduced with increasing line voltage, allowing a true power limiting operation against line variation to be implemented. When using an RCD clamp, this power limiting technique reduces maximum clamp voltage at high line. This allows for higher refl ected voltage designs as well as reducing clamp dissipation.The leading edge blanking circuit inhibits the current limitcomparator for a short time after the output MOSFET is turned on. The leading edge blanking time has been set so that, if a power supply is designed properly, current spikes caused by primary-side capacitances and secondary-side rectifi er reverse recovery time should not cause premature termination of the switching pulse.The current limit is lower for a short period after the leading edge blanking time. This is due to dynamic characteristics of the MOSFET. During startup and fault conditions the controller prevents excessive drain currents by reducing the switching frequency.Line Undervoltage Detection (UV)At power up, UV keeps TOPSwitch-HX off until the input line voltage reaches the undervoltage threshold. At power down, UV prevents auto-restart attempts after the output goes out of regulation. This eliminates power down glitches caused by slow discharge of the large input storage capacitor present in applications such as standby supplies. A single resistor connected from the VOLTAGE-MONITOR pin (Y, E/L and M packages) or MULTI-FUNCTION pin (P and G packages) to the rectifi ed DC high voltage bus sets UV threshold during power up. Once the power supply is successfully turned on, the UV threshold is lowered to 44% of the initial UV threshold to allow extended input voltage operating range (UV low threshold). If the UV low threshold is reached during operation without the power supply losing regulation, the device will turn off and stay off until UV (high threshold) has been reached again. If the power supply loses regulation before reaching the UV lowthreshold, the device will enter auto-restart. At the end of each auto-restart cycle (S15), the UV comparator is enabled. If the UV high threshold is not exceeded, the MOSFET will bedisabled during the next cycle (see Figure 11). The UV feature can be disabled independent of the OV feature.Figure 11. Typical Waveforms for (1) Power Up (2) Normal Operation (3) Auto-Restart (4) Power Down.Line Overvoltage Shutdown (OV)The same resistor used for UV also sets an overvoltage threshold, which, once exceeded, will force TOPSwitch-HX to stop switching instantaneously (after completion of the current switching cycle). If this condition lasts for at least 100 μs, the TOPSwitch-HX output will be forced into off state. Unlike with TOPSwitch-GX, however, when the line voltage is back to normal with a small amount of hysteresis provided on the OV threshold to prevent noise triggering, the state machine sets to S13 and forces TOPSwitch-HX to go through the entire auto-restart sequence before attempting to switch again. The ratio of OV and UV thresholds is preset at 4.5, as can be seen in Figure 12. When the MOSFET is off, the rectifi ed DC high voltage surge capability is increased to the voltage rating of the MOSFET (700 V), due to the absence of the refl ected voltage and leakage spikes on the drain. The OV feature can be disabled independent of the UV feature.In order to reduce the no-load input power of TOPSwitch-HX designs, the V-pin (or M-pin for P Package) operates at very low currents. This requires careful layout considerations when designing the PCB to avoid noise coupling. Traces and components connected to the V-pin should not be adjacent to any traces carrying switching currents. These include the drain, clamp network, bias winding return or power traces from otherconverters. If the line sensing features are used, then the senseresistors must be placed within 10 mm of the V-pin to minimizethe V-pin node area. The DC bus should then be routed to theline sense resistors. Note that external capacitance must notbe connected to the V-pin as this may cause misoperaton of theV pin related functions.Hysteretic or Latching Output Overvoltage Protection (OVP) The detection of the hysteretic or latching output overvoltageprotection (OVP) is through the trigger of the line overvoltagethreshold. The V-pin or M-pin voltage will drop by 0.5 V, andthe controller measures the external attached impedanceimmediately after this voltage drops. If IVor IMexceeds IOV(LS) (336 μA typical) longer than 100 μs, TOPSwitch-HX will latchinto a permanent off state for the latching OVP. It only can bereset if VVor VMgoes below 1 V or VCgoes below the power-up-reset threshold (VC(RESET)) and then back to normal.If IVor IMdoes not exceed IOV(LS)or exceeds no longer than100 μs, TOPSwitch-HX will initiate the line overvoltage and thehysteretic OVP. Their behavior will be identical to the line overvoltage shutdown (OV) that has been described in detail in the previous section.Voltage Monitor and External Current Limit Pin Table**This table is only a partial list of many VOLTAGE MONITOR and EXTERNAL CURRENT LIMIT Pin Confi gurations that are possible.

The unit is rated for a nominal output of 240 watts to power avionics, instrumentation, personal charging, lighting, and many other applications. The TC240 DC/DC Converter is FAA certified to TSO-C71 and tested to rigorous environmental standards and levels of RTCA DO-160G. The small size and light weight in conjunction with its installation flexibility (inside or outside the pressure vessel) make it an ideal choice for aircraft power needs while reducing the challenges associated with other similar products.Highlighted features include short circuit protection, overload capability, low input voltage shut-down, temperature monitoring, reverse polarity protection, a self-resettable over-temperature disable and an optional remote enable (on/off) feature.The TC240 DC/DC converter has a robust Military-rated circular connector and a rugged aluminum case which dissipates heat and provides excellent mechanical strength. It is engineered to require no external cooling and contains no internal fans or cooling methods, which saves energy, reduces weight and allows more flexible installation locations. At only 0.70 pounds, it is lighter and smaller than any other certified solution in the aviation market today.1.2 TECHNICALSPECIFICATIONSElectrical Attributes:Input Voltage: Rated 28VDC nominal, Operating 24 – 32VDC.Input Current (full load): 10 amps max at nominal input voltageOutput Voltage 5 – 18VDC adjustableOutput Power: 240 watts nominalEfficiency: 95%nominalTable 1.1Physical Attributes:Weight: 0.70 lbs (0.32 kg)Dimensions:(not including connector mate) 2.75 inches long x 3.75 inches wide x 1.29 inches high (69.9 mm long x 95.3 mm wide x 32.8 mm high)Mating Connector Kit: 6430240-1 MCIA P/N 9018654 6430240-2 MCIA P/N 9018655Mounting: Base mount – orientation not criticalTable 1.2Qualifications:Certification: FAATSO-C71Environmental Qualification: RTCA DO-160G Environmental Category; See Section 5.2 Altitude: -15,000 feet to +55,000 feetTemperature: -55°C to +70°C (-67°F to +158°F)Table 1.3SECTION 2 PRE-INSTALLATION CONSIDERATIONS2.1 COOLINGThe TC240 product does not require external cooling or contain internal active cooling. Cooling of the unit occurs exclusively through passive conduction through the base or radiated cooling across the metal case. Additional cooling can be realized through convection (exposure to free moving air) or conduction (mounting to a thermally conductive metal surface). These methods are not required to achieve rated performance but can help prevent potential overheating and extend life when the unit is operated at full power or during overload conditions. Specifically, mounting the unit to a metal surface is preferred, but not required.2.2 EQUIPMENTLOCATIONThe TC240 is designed for mounting flexibility, allowing for installation inside or outside the pressure vessel with no requirement for temperature control. In addition to altitude and temperature resistance, the unit is also designed to withstand high levels of condensing humidity. However, installation locations where the unit could be subject to standing or direct water exposure should be avoided. The unit can be mounted in any orientation. Clearance should be provided for the mating connector and may require as much as five inches past the unit connector to allow for back shell access to the connector.OFCABLES2.3 ROUTINGThe wires and cable bundle associated with the unit are heavy gauge wire and carry significant power. Be aware of routing cables near other electronics or with other wire bundles that may be susceptible to high energy flow.Avoid sharp bends in cabling and routing near aircraft control cables. Also avoid proximity and contact with aircraft structures, avionics equipment, or other obstructions that could chafe wires during flight and cause undesirable effects.2.4 LIMITATIONSThe conditions and tests for TSO approval of this article are minimum performance standards. Those installing this article, on or in a specific type or class of aircraft, must determine that the aircraft installation conditions are within the TSO standards. TSO articles must receive additional installation approval prior to being operated on each aircraft. The article may be installed only according to 14 CFR Part 43 or the applicable airworthiness requirements.The TC240 is designed to operate at full rated load (per Figure 4.1) throughout the specified environmental temperature range (per section 5.2). Note that when operating at full power, the unit case can be hot to the touch. Reference the following examples of selected conditions when operating at maximum rated load of 240 watts (stabilized after 20 minutes):∙At an ambient test temperature of +23°C when not mounted to a metal surface, the maximum case temperature can reach +62°C. (+42°C when mounted to a metal surface) ∙At an ambient test temperature of +70°C when not mounted to a metal surface, the maximum case temperature can reach +87°C. (+68°C when mounted to a metal surface)Caution and consideration should be taken with respect to aircraft installation and operation.SECTION 3 INSTALLATION PROCEDURESINFORMATION3.1 GENERALThis section contains interconnect diagrams, mounting dimensions and other information pertaining to the installation of the TC240 DC/DC Converter.

By providing a ground on theappropriate pin, the user can enable the output of the unit via a remote mounted switch. (SeeFigure 3.4)4.2.2 Input Voltage LimitIf the input voltage exceeds the over-voltage threshold (34VDC), the output will be disabled.4.2.3 Over-TemperatureThe TC240 DC/DC Converter incorporates an internal temperature sensing device thatcontinually provides monitoring and feedback to the control circuits. When the unit senses aninternal condition that exceeds maximum temperature ratings, the output is disabled. TheConverter will continue to remain shut-down until the temperature returns to within acceptablelimits. This over-temperature reset occurs automatically without external interventionrequired.4.2.4 Short Circuit And Over-CurrentThe TC240 DC/DC Converter is capable of surviving a short circuit or over-current eventwithout permanent damage or effect to long-term reliability. The unit can provide over itsrated power output up to 277 watts for over 120 minutes (until over-temperature shutdownoccurs).The Converter monitors the DC output on a pulse-by-pulse scenario to determine a short -circuit or over-current situation. If detected, the output is limited by limiting the current outputto less than 20A. If the short-circuit or over-current situation is removed, the unit will return tonormal operation.SECTION 5 CONFORMANCE 5.1 INSTRUCTIONS FOR CONTINUED AIRWORTHINESSNo periodic scheduled maintenance or calibration is necessary for continued airworthiness of theTC240 DC/DC Converter.

Wiring in series will void the warranty and destroy the batteries.•Wire lengths from PHI batteries should be identical in length and gauge in order to balance the load across all PHI batteries in the installation.•Identical wiring length is a critical feature of parallel power storage systems that must be adhered to throughout all parallel wiring instructions.•Wire lengths should be kept as short as practical.•3/8" (10 mm) lugs match the PHI 3.5 and PHI 2.7’s 3/8" (10 mm) terminal stud size.DC + bus DC – bus•Wiring from PHI batteries to DC busbars should be sized at 2 AWG or larger.•SimpliPhi recommends using Arctic Ultraflex Blue wire from Polarwire.•Energy supplied by the battery is reduced as electrical current moves through wire. For lengths of battery cable greater than ~10 ft/3 m, ensure that the voltage drop is no greater than 3%.•Wiring from the battery DC busbars to the equipment interface should be sized according to the interfacing equipment’s specifications and appropriate code requirements.Wiring Methods• 1 - 8 PHI batteries can be wired directly to DC busbars in an inverter’s power panelo See Appendix B for more details• 6 - 20 PHI batteries can be wired to a DC combiner or panelboardo See Appendix C for more details•20+ PHI batteries can be connected using common bussing directly on the batteries’ terminalsSourcing DC Combiner Boxes, Panelboards and Busbars•MidNite Solar produces the MNBCB 1000/50 Battery Combiner•Storm Power Components produces a variety of combiners and custom bussingFrom Magnum ’s Mini Magnum Panel Owner’s Manual :DC shuntDC – busDC+ bus Magnum’s Mini Magnum Panel (MMP) includes a battery positive busbar and a DC negative busbar, both rated to handle 120 Amps each. Each busbar includes seven total holes for screw type compression terminals (no ring lugs required): two holes are sized for #14 to #1/0 AWG wire and five are sized for #14 to #6 AWG wire.Note in the diagram above that the charge controller’s BAT NEG wire lands on the DC Negative Busbar, and a short wire connects the DC Negative Busbar to the top of the DC Shunt.If the DC Negat ive Busbar is utilized for battery paralleling, then the charge controller’s BAT NEG wire should instead land at the top of the DC Shunt (along with the inverter’s negative cable), and the short wire connecting the DC Negative Busbar to the DC Shunt should be moved so that the short wire lands at the bottom of the DC Shunt.From Schneider Electric’s Conext XW+ Installation Guide (975-0239-01-01_Rev M):DC – busDC+ busFrom Schneider Electric’s Conext XW+ MINI PDP Install Guide (975-0735-01-01_Rev-B):DC – busDC+ busFrom OutBack Power’s GS Load Center Installation Manual:The OutBack GS Load Center includes a single pre-installed 500Adc/50 mV shunt for landing negative battery cables.

Locating and Isolating CablesIsolating Individual Wire Pairs with the SmartTone Analog FunctionIsolating Individual Wire Pairs with the SmartTone Analog FunctionThe H position on the IT200 probe and toner lets you use the probe to trace using an analog 1kHz tone. SmartTone is intended for use on dry pairs of wires that are un-terminated at both ends of the run. It is not intended to be used on live wires with a DC power source (e.g., live telephone lines), nor will it work on wire pairs that are carrying AC signals. SmartTone works on many types of wire pairs including twisted pair, house wiring, and coax (the shield is one wire and the center conductor is the other wire of the pair). SmartTone Positive Identification1.The toner red lead must be connected to one ofthe wires of the pair, and the black lead must beconnected to the other wire of the pair.2.Put the toner and probe in the H position.3.At the far end of the cable run, place the probenear the wires you are tracing. Pick the pair thatgives the loudest signal in the toner speaker.4.Short and release the two wires of the pair. Ifyou hear a change in the pattern of the tone,then you have located the target pair of wires.If you don’t hear a change in the tone pattern,then pick a different pair and try again untilyou find the pair that causes the tone patternto change.Users ManualValidating RJ11 and RJ45 Cable Maps You can use the IT200 or IT100 toner and IT200 probe to validate the cable map on RJ11 and RJ45 connectors. The cable map function finds the most common wiring faults on twisted pair cabling: shorts, opens, and crossed pairs.1.Connect an IT200 or IT100 toner to a RJ11 or RJ45jack, as shown in Figure 1.2.Turn the toner’s rotary switch to M3.If necessary, use the IP200 probe to locate the correctconnector at the other end of the cabling, asdescribed in the previous section.4.Connect the IP200 probe to the RJ11 or RJ45 jack;then turn the probe’s rotary switch to CABLE MAP.5.The probe’s LEDs and beeper indicate the cable map,as follows:•The number of each LED corresponds to a pin on the connector. You can enable the SYNC LED tovalidate the shield. See “Validating the Cable’sShield” on page 12. •Each LED that corresponding to an active pin flashes briefly, then should light for about 1second. The brief flash shows which LED is nextin the sequence.•The probe also beeps in different tones to indicate good wiring, miswires, shorts, andopens.•Miswire: If one LED flashes briefly, then another LED lights for one second, the wire for the firstLED is miswired to the pin for the second LED. •Short: If two LEDs turn on for 1 second at the same time, those two pins are shorted together.If more than 2 wires are shorted together, theLEDs for the shorted pins indicate opens. •Open: If an LED flashes briefly, then no LEDs turn on, that pin is open.Validating RJ11 and RJ45 Cable Mapsash05f.eps Figure 2.

Nitrendipine is a calcium channel blocker with marked vasodilator action.
Target: Calcium Channel Nitrendipine is a dihydropyridine calcium channel blocker. It is used in the treatment of primary hypertension to decrease blood pressure. Nitrendipine blocked Ca2+ currents very potently, with half-block by subnanomolar concentrations. The concentration dependence of block had the form expected for 1:1 binding, with an apparent dissociation constant (Kd) of 0.36 nM. In contrast, when cells were held at hyperpolarized potentials, nitrendipine blocked Ca2+ currents much less potently (Kd approximately equal to 700 nM) [1, 2]. Nitrendipine, a potent analogue of nifedipine, binds in a References:
