Supertex inc.HV9910BDB7HV9910B PFC 40W LED Driver DemoboardSpecificationsActual Size: 3.0” x 2.3” x 1.1”Top View Bottom ViewGeneral DescriptionThe Supertex HV9910BDB7 demonstrates the use of an HV9910B control IC in an off-line, High Brightness LED driver application. The board incorporates power factor correction (PFC) and satisfies the limits for harmonic currents according to the EN61000-3-2 Class C standard having total harmonic distortion (THD) less than 20%. The board features a low component count and long life operation due to the absence of electrolytic capacitors. The board is designed to supply a string of LEDs with a current of 350mA and a voltage in the 65 to 105V range from a 220/230VAC line.The conversion stage draws line current throughout the AC line cycle, partly using a charge pumping and partly using a boost conversion technique to charge the bulk energy storage capacitors. The LED current is provided with a continuous mode buck stage giving a DC current with about 30% peak-to-peak ripple. A patent for this conversion technique is pending. Please inquire with the Supertex applications department for design guidance, should change of input line voltage, output voltage, or output current be desired.An effort was made to satisfy the requirements of CISPR 15 (EN55015), limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment.The connection diagram details the hookup of the board to the AC line. Note that the load is NOT galvanically isolated, and that measurements to the board require measurement techniques in common use with non-isolated off-line power supplies (isolation transformers, differential probes, etc).Board LayoutSchematic DiagramConnection Diagram220VAC105VDC 350mADCConnectionsI nput Voltage - Connect the AC line input voltage to AC VIN as shown.LED String - Connect the LED strings between LED+ and LED- as shown (anode of the string to LED+ and cathode to LED-).Figure 3.

超特克HV9918DB1高流LED驱动示例板说明书

Supertex inc.HV9918DB1High Current LED Driver DemoboardThe HV9918DB1 demoboard is a high current LED driver designedto drive one or two LEDs at 700mA from a 9.0 - 16VDC input. Thedemoboard uses Supertex’s HV9918 hysteretic buck LED driver IC.The HV9918DB1 includes digital control of PWM dimming, which allows the user to dim the LEDs using an external, TTL-compatible square wave source applied between DIM and GND . In this case, the PWM dimming frequency and duty ratio are set by the external square wave source.The demoboard is protected against short circuit and open LEDconditions. It also includes thermal derating of the LED current us-ing an external NTC resistor to prevent over-heating.The bottom of the HV9918DB1 is an exposed copper plane (con-nected to the input ground) which can be connected to a 1” square heatsink (eg: 374324B00035G from Aavid Thermalloy) to allow for operation in higher ambient temperatures without tripping the HV9918’s built-in over temperature protection.General DescriptionInput Connection: Connect the input DC voltage between VIN andGND terminals.Output Connection:Connect the LED(s) between LED+ (anode of LED string) and LED- (cathode of LED string) ter-minals.PWM Dimming Connection:1. If no PWM dimming is required, short PWMD and VDD terminals.2. If dimming using an external PWM dimming source, connect the PWM source between the PWMD and GNDterminals.NTC Thermistor Connection:1. If no thermal derating is required, the NTC terminalcan be left open.2. If thermal derating of the LED current is required, the NTC thermistor can be connected between NTCand GND terminals as shown.ConnectionsSilk ScreenOperation of the BoardThe HV9918DB1 uses Supertex’s HV9918 hysteretic buck LED driver IC to control the LED current. Since the regula-tion method controls both the peak and the valley current in the inductor, the demoboard has excellent line and load regulation.The LED current can be controlled in by PWM dimming. PWM dimming can be achieved in one of two ways:1. Analog control of PWM dimming where a 0-2V sourcecan be applied between NTC and GND terminals (the NTC terminal can also be used for thermal derating of the LED current as explained in the next section).2. Direct control of PWM dimming by applying a TTL com-patible square wave source between PWMD and GND terminals.Analog Control of PWM Dimming / Thermal De-ratingAnalog Control of PWM dimming can be accomplished by applying a 0 – 2.0V DC voltage between NTC and GND (the DC voltage must have a 500μA source/sink capability). In this case, PWMD is connected to VDD and the LEDs are dimmed at 1.0kHz (as set by the capacitor at the RAMP pin of the IC). The duty cycle of the LED current can be adjusted by varying the external voltage at NTC (0V = 0% LED cur-rent and 2.0V = 100% LED current).The same NTC terminal can instead be used to de-rate the LED current based on the LED temperature, if desired. This would reduce the LED current as the LED temperature rises and prevents over-heating of the LED. An NTC resistor can be used to sense the temperature of the LED and this resis-tor can be connected between the NTC and GND terminals of the HV9918DB1. The demoboard is designed to operate with a 100k NTC thermistor which has a B-constant of 4250 (eg: NCP18WF104 from Murata). With this NTC thermistor, the LED current will start dropping at 85ºC and will reach about 350mA at 125ºC.Thermal derating in the HV9918DB1 uses the analog control of PWM dimming function to limit the LED current when the LED temperature rises. During normal operating mode (con-stant LED current; no PWM dimming), the LED current will be PWM dimmed at 1.0kHz. During PWM dimming mode, the thermal derating function limits the maximum PWM dim-ming duty cycle so that the LED current does not exceed the maximum allowable current determined by the thermal derating circuit.Direct Control of PWM DimmingIn the direct control method, the PWM dimming of the LEDs is achieved by driving the PWMD terminal using an external square wave source. In this case, PWM dimming frequency and duty cycle are set by the external source.In this mode, if the thermal derating function is not desired, NTC terminal should be left open. In this case, the recom-mended PWM dimming frequency can be anything up to 10kHz.If thermal derating is desired, then the NTC thermistor should be connected between the NTC and GND terminals. In this case, the PWM dimming frequency should be greater than 1.2kHz.Fig. 1. Normal Operation – Drain Voltage and LED CurrentFig. 2. PWM Dimming WaveformFig. 3.

Thermal Derating of the LED CurrentII Normal inductor current waveformII 0Note:The increase in the LED current at 9.0V input and 6.7V output can be explained by the fact that when the dif-ference between the input and output voltages is very small, the rising inductor current waveform becomes more exponential rather than linear (the falling edge of the inductor current remains linear because the output voltage is high). This causes the average inductor (and therefore LED) current to increase even though the up-per and lower bounds are still the sameHV9918DB1 Schematic DiagramHV9918DB1 WaveformsSupertex 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.

超特克LED驱动演示板HV9930DB1说明书

Supertex inc.HV9930DB1General DescriptionThe HV9930DB1 is an LED driver demoboard capable of driving up to 7 1-watt LEDs in series from an automotive input of 9 - 16VDC. The demoboard uses Supertex’s HV9930 in a boost-buck topology. The converter operates at frequencies in excess of 300kHz and has excellent output current regulation over the input voltage range. It can also withstand transients up to 42V and operate down to 6V input. The converter is also protected against open LED and output short circuit conditions. Protection against reverse polarity up to 20V is also included.Board Layout and Connection DiagramHigh Bright LED Driver IC DemoboardMeeting Automotive RequirementsConnections:Input - The input is connected between the terminals of connector J1 as shown in the Connection Diagram.Output - The output is connected between the terminals of connector J2 as shown.Enable/PWM Dimming:To just enable the board, short pins 1 and 2 of connector J3 as shown. For PWM dimming, connect the external push-pullsquare wave source between terminals 1 and 3 of connectorJ3 as shown by the dotted lines.Note: During PWM dimming, pin 2 of connector J3 should be left open. Also, the PWM signal must have the proper polarity with the positive connected to pin 1 of J3. Note that pin 3 of J3 is internally connected to the return path of the input voltage.Actual Size: 2.25” x 1.25”PWM DimmingV INTesting the Demo BoardNormal Operation: Connect the input source and the output LEDs as shown in the Connection Diagram and enable the board. The LEDs will glow with a steady intensity. Connect-ing an ammeter in series with the LEDs will allow measure-ment of the LED current. The current will be 350mA +/- 5%.Open LED test: Connect a voltmeter across the output ter-minals of the HV9930DB1. Start the demoboard normally, and once the LED current reaches steady state, unplug one end of the LED string from the demoboard. The output volt-age will rise to about 33V and stabilize.Short Circuit Test: When the HV9930DB1 is operating in steady state, connect a jumper across the terminals of the LED string. Notice that the switching frequency drops, but the average output current remains the same.PWM Dimming: With the input voltage to the board discon-nected, apply a TTL compatible, push-pull square wave sig-nal between PWMD and GND terminals of connector J3 as shown in the Connection Diagram. Turn the input voltage back on and adjust the duty cycle and / or frequency of the PWM dimming signal. The output current will track the PWMdimming signal. Note that although the converter operates perfectly well at 1.0kHz PWM dimming frequency, the best PWM dimming ratios can be obtained at lower frequencieslike 100 or 200HzTypical ResultsFig. 1 shows the efficiency plot f or the HV9930DB1 over the input voltage range. The converter has efficiencies greater than 80% over 13V input. Note that these measurements do not include the 0.3 - 0.5W loss in the reverse blocking diode.Fig. 2 shows the variation of the switching frequency over the input votage range. The frequency varies from 300kHz to 500kHz over the entire input voltage range and avoids the restricted frequency band of 150kHz to 300kHz and the AM band greater than 530kHz. This makes it easier to meet the conducted and radiated EMI specifications for the automo -tive industry.Fig.3 shows the output current variation over the input volt-age range. The LED current has a variation of about 2.0mA over the entire voltage range.7072747678808284Input Voltage (V)E f f i c i e n c y (%)300350400450500Input Voltage (V)S w i t c h i n g F r e q u e n c y (k H z )348.0348.5349.0349.5350.0350.5Input Voltage (V)O u t p u t C u r r e n t (m A )Fig. 3 Output Current vs. Input VoltageThe waveforms in Fig.4 show the drain voltage of the FET (channel 1 (blue); 10V/div) and the LED current (channel 4 (green); 100mA/div) at three different operating conditions – 9.0V in, 13.5V in and 16V in.Fig. 5 shows the operation of the converter during cold crank conditions as the input voltage decreases from 13.5V to 6V and increases back to 13.5V. In these cases, the input current reaches the limit set and the output current drops correspondingly. Thus, the LEDs continue to glow, but with reduced intensity. Once the voltage ramps back up, the out-put current goes back to its normal value and the converter comes out of the input current limit.Fig.6 shows the LED current during an input step change from 13.5 to 42V and back to 13.5V (similar to a clamped load dump). It can be seen that the LED current drops brieflywhen the input voltage jumps, but there are no overshoots.(a)(b)(c)Fig. 4. Steady State Waveforms(a): 9.0V in; (b): 13.5V in; (c): 16V inFig. 5.

In both cases, it can be seen that the HV9930DB1 can easily withstand faults and come back into normal operation almost instantly.Fig. 8 shows the PWM dimming performance of the HV9930DB1 with a 100Hz, 3.3V square wave signal. The converter can easily operate at PWM dimming duty cyclesfrom 1% - 99%.(a): Open LED Condition(b): Output Short CircuitFig. 7 HV9930DB1 during output fault conditionsFET drain voltage (20V/div)Channel 1 in (a); Channel 2 in (b)Channel 4 (green): LED currentShort Circuit(a)(b)(c)Fig. 8 PWM Dimming at 100HzChannel 1 (blue): PWM Dimming Input Signal (2V/div)Channel 4 (Green): LED current (100mA/div)Fig. 9 shows the rise and fall times of the output current dur-ing PWM dimming. The converter has nearly symmetric rise and fall times of about 25µs. These rise and fall times can be reduced (if desired) by reducing the output capacitance C10. However, this will lead to increased ripple in the output current.Conducted EMI Tests on theHV9930DB1In preliminary tests conducted on the demo board, the board meets SAE J1113 Class 3 conducted EMI standards without the need for any input filters (other than the input capacitors already included). This is a result of the combination of the continuous input current and a localized switching loop (Q1 – C1 – D3).Table 1 details the conducted EMI limit as per SAE J1113 and the maximum conducted EMI obtained from measure-ments on the board. The table also lists the Class of the SAE standard the board meets in each frequency range.The conducted EMI plots for the HV9930DB1 obtained at an input voltage of 13.5V and an LED string voltage of 27V(output current is 350mA) are given in the Appendix.

MIC3202 MIC3202-1高亮LED驱动器评估板说明书

MIC3202/MIC3202-1Evaluation BoardHigh-Brightness LED Driver with IntegratedMOSFET and High-Side Current Sense Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 (408) 944-0800 • fax + 1 (408) 474-1000 • General DescriptionThe MIC3202/MIC3202-1 is a hysteretic step-down,constant-current, High-Brightness LED (HB LED) driver.It provides an ideal solution for interior/exterior lighting,architectural and ambient lighting, LED bulbs, and othergeneral illumination applications.This board enables the evaluation of theMIC3202/MIC3202-1 for 1A LED current. The board isoptimized for ease of testing, with all the components ona single side. The device operates from a 6V to 37Vinput voltage range, and includes an integrated 1.0AMOSFET. When the input voltage approaches andcrosses UVLO threshold, the internal 5V V CC isregulated and the integrated MOSFET is turned on if ENpin and DIM pin are high. The inductor current builds uplinearly. When the CS pin voltage hits the V CS(MAX) withrespect to V IN,the internal MOSFET is turned off and theSchottky diode takes over and returns the current to V IN.Then the current through inductor and LEDs startsdecreasing. When CS pin hits V CS(MIN), the internalMOSFET is turned on and the cycle repeats.Since the control scheme does not need loopcompensation, it makes for a very simple design andavoids problems of instability.Datasheets and support documentation can be found onMicrel’s web site at: .RequirementsThis board needs a single-bench power sourceadjustable over the input voltage of 6V < V IN < 37V thatcan provide at least 1A of current. The loads can eitherbe active (electronic load in CV mode) or passive(LEDs) with the ability to dissipate the maximum loadpower while keeping accessible surfaces ideally <70°C.PrecautionsThere is no reverse input protection on this board. Whenconnecting the input sources, ensure that the correctpolarity is observed.In the line transient condition, such as hot plug-in, anelectrolytic capacitor may be required at the VIN andGND terminals in order to prevent IC damage from asurge voltage.Getting Started1. Connect V IN supply to the input VIN and GNDterminals. With the output of this supply disabled,set the supply voltage to the desired input testvoltage (6V < V IN < 37V). This supply voltage shouldbe monitored at the test boards input terminals toallow voltage drops in the test cables (and ammeterif used) to be accounted for. An ammeter can beadded inline with the +VIN input terminal toaccurately measure input current.2. Connect the LEDs to the output terminalsbetween LED+ and LED−. This LED voltage dropdepends on manufacturer tolerance and number ofLEDs. The LED current can be measured using anammeter or current probe. A 4.7µF ceramiccapacitor helps to reduce the current ripple throughthe LED. The LED current is set to 1A by a 200mΩcurrent-sense resistor (R CS).3. Enable the input supply. By default, the IC isenabled when the input voltage crosses the VINthreshold (4V) and the internal VCC regulator andinternal MOSFET are turned on with the EN andDIM pins are high. To use the EN and DIM functionsof the MIC3202/MIC3202-1, a test point is providedfor each of them.Ordering InformationPart Number DescriptionMIC3202YME EV MIC3202YME Evaluation BoardOther FeaturesEN InputThe EN pin provides a logic level control of the output and the voltage has to be 2.0V or higher to enable the current regulator. The output stage is gated by the DIM pin. When the EN pin is pulled low, the regulator goes to off-state and the supply current of the device is reduced to below 1µA. Do not drive the EN pin above the supply voltage. DIM InputThe DIM pin provides a logic level control for brightness of the LED. A PWM input can be used to control the brightness of LED. DIM high enables the output and its voltage has to be 2.0V or higher. DIM low disables the output, regardless of EN high-state. Current-Sense InputThe CS pin provides the high-side current sense to set the LED current with an external sense resistor.A sense resistor R CS is placed between V IN and LED+ terminals.The current through LED is sensed by the sense resistor (R CS ). The sensed voltage is fed back to the MIC3202 to regulate the LED current R CS is given by:)I V +V (x 21=R LED)MIN (CS )MAX (CS CS Error!Bookmark not defined.I LED is LED current required to set.R CS (Ω) I LED (A)I 2R (W)Size (SMD)1.33 0.15 0.03 0603 0.56 0.35 0.07 0805 0.4 0.5 0.1 0805 0.28 0.7 0.137 0805 0.2 1.0 0.2 1206For V CS(MAX) and V CS(MIN) refers to the Electrical Characteristics table.

Frequency DitheringThe MIC3202 is designed to modulate the V CS(MAX) with amplitude ±6mV by a pseudo random generator to generate the ±12% of the switching frequency dithering.

超特克HV9910BDB3高电压高流LED驱动示波板说明书

Supertex inc.HV9910BDB3General DescriptionThe HV9910BDB3 demoboard is a high current LED driver designed to drive one LED or two LEDs in series at currents up to 1.0A from a 10 – 30VDC input. The demoboard uses Supertex’s HV9910B Universal LED driver IC to drive a buck converter.The HV9910BDB3 can be configured to operate in either a constant frequency mode (for driving a single LED) or in a constant off-time mode (for driving two LEDs).The output current can be adjusted in two ways – either with linear dimming using the onboard potentiometer or with PWM dimming by applying a TTL – compatible square wave signal at the PWMD terminal. Using linear dimming, the output current of the HV9910DB1 can be lowered to about 0.01A (note: zero output current can be obtained only by PWM dimming).Connection DiagramLow Voltage, High Current,LED Driver DemoboardConnections1. Input Connection - Connect the input DC voltage between VIN and GND terminals of connector J1 as shown in the connection diagram.2. Output Connection - Connect the LEDs between LED+ (anode of LED string) and LED- (cathode of LED string) of connector J2.a. If the load is one LED, short the RT and FREQ terminals of connector J4 using a jumper.b. If the load is two LEDs, short the RT and OFFT terminals of connector J4 using a jumper.3. PWM Dimming Connectiona. If no PWM dimming is required, short PWMD and VDD terminals of connector J3.b. If PWM dimming is required, connect the TTL-compatible PWM sourc between PWMD and GND terminals of connector J3. The recommended PWMdimming frequency is ≤ 1.0kHz.Short for constantfrequency modeFrequently Asked Questions1. Why does the demoboard have two operating modes?Constant frequency mode limits the maximum output voltage to less then 50% of the minimum input voltage. So, in this case, if we use only the constant frequency mode, the maximum output voltage will have to be less than 5V. Constant off-time mode removes this limita-tion and allows the output voltage become higher. How-ever, in order to achieve reasonable noise immunity and to limit the switching frequency variation over the input voltage range, it is not recommended to operate the HV9910DB3 with the output voltage exceeding 80% of the input voltage, even in the constant off-time mode. Please refer to application note AN-H50 on the Supertex website for more details.2. If the minimum input voltage in my application is high-er (say 20V), does that mean I can drive a 9V LED stringin the constant frequency mode or an 16V LED string inthe constant off-time mode using the demoboard?Although a larger LED string can be driven using the demoboard in these conditions, the demoboard will not be able to drive the LED at 1A.The HV9910B is a constant peak current controller. Theaverage LED current is equal to the peak current set (using the sense resistor) minus one-half of the ripple current in the inductor.Higher output voltages lead to larger ripple current val-ues, which will reduce the maximum LED current the board can deliver.3. How can I compute the maximum LED current thedemoboard can deliver if I use a higher input voltage and a higher LED string voltage?See table below:ParametersMinimum input voltage Maximum LED string voltageSwitching frequency (constant frequency mode) Off-Time (constant off-time mode)HV9910B CS threshold voltage Sense Resistor Inductor= V IN,MIN = V O,MAX = f S = T OFF = V CS = R CS = L(100kHz)(5.1μs)(0.25V)(0.22Ω)(220μH)Constant Off-Time ModeConstant Frequency ModeV O,MAX • T OFF LΔl =I LED = –V CS R CS Δl 2V O, MAX V IN,MIN 1 –Maximum Switching Frequency ={{T OFFV O, MAX V IN,MIN1 –{{L • f SV O,MAX • I LED = –V CS R CS Δl2Δl =Frequently Asked Questions (cont.)4. If the constant off-time mode allows a wider LED volt-age range, why not use that mode exclusively? Why do we need the constant frequency mode?Although the constant off-time mode allows the demoboard to operate at a higher output voltage, the LED ripple current is directly proportional to the output voltage in this mode. This makes it difficult to get a good load regulation of the LED current in the constant off-time mode with a wide variation in the LED string voltage (in this case it will be a 1:4 variation). At lower LED volt-age values, the ripple will be lower and the LED current would be higher.By switching between the two modes depending on the load, we can get a better current accuracy without hav-ing to adjust the LD voltage or the sense resistor.5. Why is the efficiency of the demoboard higher with aload of two LEDs compared to a single LED load?Losses in the HV9910BDB3 occur due mainly due to two factors: a. Conduction losses in the FET and diode b. Switching losses in the FET Switching losses are dependent on the switching fre-quency, input voltage and total parasitic capacitance at the node. At higher switching frequencies, the switching losses are higher.Conduction losses are dependent on the duty cycle. Since the voltage drop on the FET is smaller than the voltage drop on the diode (the on-resistance of the FET is very small), the higher the duty cycle, the smaller is the conduction loss. Please note that we are ignoring the losses in the inductor, which will be identical in both cases.Also, efficiency = P OUT / P IN = P OUT / (P OUT + losses) = 1/ (1 + losses/P OUT ), where P OUT is the output power and P IN is the input power. So, if the output power is higher, the fixed switching losses are a smaller fraction of the output power and thereby the efficiency is higher.Comparing the operation of the converter in both modes at 12V input for this particular demoboard, the following are the differences:a. Output power is higher with 2 LEDs as the loadb. Switching frequency in the constant off-time mode is 55kHz, whereas it is 100kHz in the constant frequency modec. Duty cycle of operation is about higher in the con-stant off-time mode by a factor of 2 than in the con-stant frequency mode All the above factors favor the higher load voltage and thusthe demoboard has a higher efficiency when the load is larg -er.6. Why are the LED current rise and fall times during PWM dimming different when the load changes from one LED to two LEDs?The LED current rise time is directly proportional to V IN - V OUT and the fall time is proportional to V OUT (where V IN is the input voltage and V OUT is the output voltage). Since V OUT is higher with two LEDs, the rise time will be larger and the fall time will be smaller.Load Regulation (@ V IN = 12V)0246810Load Voltage (V)C h a n g e i n c u r r e n t (%)Constant Off-Time ModeTypical ResultsConstant Frequency Mode:The HV9910BDB3 is designed to be operated in the con-stant frequency mode when the load is a single LED.
