TION KIT EVALUA BLE AVAILA
1Gbps to 11.3Gbps, SFP+ Laser Driver with Laser Impedance Mismatch Tolerance
General Description
The MAX3946 is a +3.3V, multirate, low-power laser diode driver designed for Ethernet and Fibre Channel transmission systems at data rates up to 11.3Gbps. This device is optimized to drive a differential transmitter optical subassembly (TOSA) with a 25I flex circuit. The unique design of the output stage enables use of unmatched TOSAs, greatly reducing headroom limitations and lowering power consumption. The device receives differential CML-compatible signals with on-chip line termination. It can deliver laser modulation current of up to 80mA, at an edge speed of 22ps (20% to 80%), into a 5I to 25I external differential load. The device is designed to have a symmetrical output stage with on-chip back terminations integrated into its outputs. A high-bandwidth, fully differential signal path is implemented to minimize deterministic jitter. An equalization block can be activated to compensate for the SFP+ connector. The integrated bias circuit provides programmable laser bias current up to 80mA. Both the laser bias generator and the laser modulator can be disabled from a single pin. A 3-wire digital interface reduces the pin count and permits adjustment of input equalization, pulse-width adjustment, Tx polarity, Tx deemphasis, modulation current, and bias current without the need for external components. The MAX3946 is available in a 4mm x 4mm, 24-pin TQFN package.

3956fTypical applicaTionFeaTuresapplicaTionsDescripTionConstant-Current,Constant-Voltage Converter The L T ®3956 is a DC/DC converter designed to operate as a constant-current source and constant-voltage regulator . It is ideally suited for driving high current LEDs. It features an internal low side N-channel power MOSFET rated for 84V at 3.3A and driven from an internal regulated 7.15V supply. The fixed frequency, current-mode architecture results in stable operation over a wide range of supply and output voltages. A ground referenced voltage FB pin serves as the input for several LED protection features, and also makes it possible for the converter to operate as a constant-voltage source. A frequency adjust pin allows the user to program the frequency from 100kHz to 1MHz to optimize efficiency, performance or external component size.The L T3956 senses output current at the high side of the LED string. High side current sensing is the most flexible scheme for driving LEDs, allowing boost, buck mode or buck-boost mode configuration. The PWM input provides LED dimming ratios of up to 3000:1, and the CTRL input provides additional analog dimming capability.94% Efficient 25W White LED Headlamp Drivern3000:1 T rue Color PWM TM Dimming n Wide Input Voltage Range: 4.5V to 80V n Output Voltage Up to 80V n Internal 3.3A/84V Switchn Constant-Current and Constant-Voltage Regulation n 250mV High Side Current SensenDrives LEDs in Boost, Buck Mode, Buck-Boost Mode, SEPIC or Flyback Topologyn Adjustable Frequency: 100kHz to 1MHz n Open LED Protectionn Programmable Undervoltage Lockout with Hysteresis n Constant-Voltage Loop Status Pin n PWM Disconnect Switch Drivern CTRL Pin Adjusts High Side Current Sense Threshold n Low Shutdown Current: <1µA n Programmable Soft-Startn Available in the 36-Lead (5mm × 6mm) QFN PackagenHigh Power LED n Battery Chargern Accurate Current Limited Voltage RegulatorV , 6V TO 60V 25W LED STRINGEfficiency vs V INV IN (V)02080E F F I C I E N C Y (%)848892961004060803956 TA01bL , L T , L TC, L TM, Linear Technology and the Linear logo are registered trademarks andT rue Color PWM is a trademark of Linear Technology Corporation.

FB is intended for con-stant-voltage regulation or for LED protection/open LED detection. The internal transconductance amplifier with output V C will regulate FB to 1.25V (nominal) through the DC/DC converter . If the FB input is regulating the loop, the VMODE pull-down is asserted. This action may signal an open LED fault. If FB is driven above the FB threshold (by an external power supply spike, for example), the VMODE pull-down will be de-asserted and the PWMOUT pin will be driven low to protect the LEDs from an overcurrent event. Do not leave the FB pin open. If not used, connect to GND.ISN: Connection point for the negative terminal of the current feedback resistor . If ISN is greater than 2.9V , the LED current can be programmed by I LED = 250mV/R LED when V CTRL > 1.2V or I LED = (V CTRL –100mV)/(4 • R LED ) if V CTRL < 1V. Input bias current is typically 20µA. Below 3V , ISN is an input to the short-circuit protection feature that forces GATE to 0V if ISP exceeds ISN by more than 350mV (typ).ISP: Connection point for the positive terminal of the current feedback resistor . Input bias current for this pin depends on CTRL pin voltage, as shown in the Typical Performance Characteristics. ISP is an input to the short-circuit protec-tion feature when ISN is less than 3V .V C : T ransconductance Error Amplifier Output Pin. This pin is used to stabilize the voltage loop with an RC network. This pin is high impedance when PWM is low, a feature that stores the demand current state variable for the next PWM high transition. Connect a capacitor between this pin and GND; a resistor in series with the capacitor is recommended for fast transient response.CTRL: Current Sense Threshold Adjustment Pin. Regula-ting threshold V (ISP – ISN) is 0.25 • V CTRL plus an offset for 0V < V CTRL < 1V . For V CTRL > 1.2V the current sense threshold is constant at the full-scale value of 250mV . For 1V < V CTRL < 1.2V , the dependence of the current sense threshold upon V CTRL transitions from a linear function to a constant value, reaching 98% of full-scale value by V CTRL = 1.1V . Connect CTRL to V REF for the 250mV default threshold. Do not leave this pin open.NC: No Internal Connection. These pins may be left floating or connected to an adjacent pin.EN/UVLO: Shutdown and Undervoltage Detect Pin. An accurate 1.22V falling threshold with externally program-mable hysteresis detects when power is OK to enable switching. Rising hysteresis is generated by the external resistor divider and an accurate internal 2.1µA pull-down current. Above the 1.24V (nominal) threshold (but below 6V), EN/UVLO input bias current is sub-µA. Below the falling threshold, a 2.1µA pull-down current is enabled so the user can define the hysteresis with the external resis-tor selection. An undervoltage condition resets soft-start. Tie to 0.4V , or less, to disable the device and reduce V IN quiescent current below 1µA.INTV CC : Regulated supply for internal loads, GATE driver and PWMOUT driver . Supplied from V IN and regulates to 7.15V (typical). INTV CC must be bypassed with a 4.7µF capacitor placed close to the pin. Connect INTV CC directly to V IN if V IN is always less than or equal to 7V .GND: Ground. The exposed pad, Pin 37, is ground and must be soldered directly to the ground plane. V IN : Input Supply Pin. Must be locally bypassed with a 0.22µF (or larger) capacitor to PGND placed close to the IC.SW: The exposed pad, Pin 38, is the drain of the switch-ing N-channel MOSFET and must be connected to the external inductor .PGND: Source terminal of switch and the GND input to the switch current comparator . Kelvin connect to the GND plane close to the IC using Pin 12. Pins 13 to 17 should be connected externally to the PGND terminals of components in the switching path. See the Board Layout section. PWMOUT: Buffered Version of the PWM Signal. This pin is used to drive the LED load disconnect N-channel MOSFET or level shift. This pin also serves in a protection function for the FB overvoltage condition—will toggle if the FB input is greater than the FB regulation voltage (V FB ) plus 60mV (typical). The PWMOUT pin is driven from INTV CC . Use of a MOSFET with gate cut-off voltage higher than 1V is recommended./3956fblock DiagraMV REF : Voltage Reference Output Pin (typically 2V). This pin drives a resistor divider for the CTRL pin, either for analog dimming or for temperature limit/compensation of LED load. Can supply up to 100μA.PWM: A signal low turns off switcher , idles oscillator and disconnects V C pin from all internal loads. PWMOUT pin follows PWM pin. PWM has an internal pull-down resistor . If not used, connect to INTV CC .VMODE : An open-collector pull-down on VMODE asserts if the FB input is greater than the FB regulation threshold minus 50mV (typical). To function, the pin requires an external pull-up resistor . When the PWM input is low and the DC/DC converter is idle, the VMODE condition is latched to the last valid state when the PWM input washigh. When PWM input goes high again, the VMODE pin will be updated. This pin may be used to report an open LED fault. Use a pull-up current less than 1mA.SS: Soft-Start Pin. This pin modulates oscillator fre-quency and compensation pin voltage (V C ) clamp. The soft-start interval is set with an external capacitor . The pin has a 10µA (typical) pull-up current source to an internal 2.5V rail. The soft-start pin is reset to GND by an undervoltage condition (detected by EN/UVLO pin) or thermal limit.RT: Switching Frequency Adjustment Pin. Set the fre-quency using a resistor to GND (for resistor values, see the Typical Performance curve or Table 1). Do not leave the RT pin open.pin FuncTions/operaTionThe LT3956 is a constant-frequency, current mode converter with a low side N-channel MOSFET switch. The switch and PWMOUT pin drivers, and other chip loads, are powered from INTV CC, which is an internally regulated supply. In the discussion that follows, it will be helpful to refer to the Block Diagram of the IC. In normal operation, with the PWM pin low, the power switch is turned off and the PWMOUT pin is driven to GND, the V C pin is high impedance to store the previous switching state on the external compensation capacitor, and the ISP and ISN pin bias currents are reduced to leakage levels. When the PWM pin transitions high, the PWMOUT pin transitions high after a short delay. At the same time, the internal oscillator wakes up and generates a pulse to set the PWM latch, turning on the internal power MOSFET switch. A voltage input proportional to the switch current, sensed by an internal current sense resistor, is added to a stabilizing slope compensation ramp and the resulting switch-current sense signal is fed into the positive termi-nal of the PWM comparator. The current in the external inductor increases steadily during the time the switch is on. When the switch-current sense voltage exceeds the output of the error amplifier, labeled V C, the latch is reset and the switch is turned off. During the switch off phase, the inductor current decreases. At the completion of each oscillator cycle, internal signals such as slope compensa-tion return to their starting points and a new cycle begins with the set pulse from the oscillator.Through this repetitive action, the PWM control algorithm establishes a switch duty cycle to regulate a current or voltage in the load. The V C signal is integrated over many switching cycles and is an amplified version of the differ-ence between the LED current sense voltage, measured between ISP and ISN, and the target difference voltage set by the CTRL pin. In this manner, the error amplifier sets the correct peak switch-current level to keep the LED current in regulation. If the error amplifier output increases, more current is demanded in the switch; if it decreases, less current is demanded. The switch current is monitored during the on-phase and is not allowed to exceed the current limit threshold of 3.9A (typical). If the SW pin exceeds the current limit threshold, the SR latch is reset regardless of the output state of the PWM compara-tor. Likewise, at an ISP/ISN common mode voltage less than 3V, the difference between ISP and ISN is monitored to determine if the output is in a short-circuit condition. If the difference between ISP and ISN is greater than 335mV (typical), the SR latch will be reset regardless of the PWM comparator. These functions are intended to protect the power switch, as well as various external components in the power path of the DC/DC converter.In voltage feedback mode, the operation is similar to that described above, except the voltage at the V C pin is set by the amplified difference of the internal reference of 1.25V (nominal) and the FB pin. If FB is lower than the reference voltage, the switch current will increase; if FB is higher than the reference voltage, the switch demand current will decrease. The LED current sense feedback interacts with the FB voltage feedback so that FB will not exceed the internal reference and the voltage between ISP and ISN will not exceed the threshold set by the CTRL pin. For accurate current or voltage regulation, it is necessary to be sure that under normal operating conditions, the appropriate loop is dominant. To deactivate the voltage loop entirely, FB can be connected to GND. To deactivate the LED current loop entirely, the ISP and ISN should be tied together and the CTRL input tied to V REF .T wo LED specific functions featured on the L T3956 are controlled by the voltage feedback pin. First, when the FB pin exceeds a voltage 50mV lower (–4%) than the FB regulation voltage, the pull-down driver on the VMODE pin is activated. This function provides a status indicator that the load may be disconnected and the constant-voltage feedback loop is taking control of the switching regulator. When the FB pin exceeds the FB regulation voltage by 60mV (5% typical), the PWMOUT pin is driven low, ignoring the state of the PWM input. In the case where the PWMOUT pin drives a disconnect NFET, this action isolates the LED load from GND, preventing excessive current from damaging the LEDs. If the FB input exceeds the overvolt-age threshold (1.31V typical), then an externally driven overvoltage event may have caused the FB pin to be too high and the VMODE pull-down will be deactivated until the FB pin drops below the overvoltage threshold./3956f3956fapplicaTions inForMaTionINTV CC Regulator Bypassing and OperationThe INTV CC pin requires a capacitor for stable operation and to store the charge for the switch driver and PWMOUT pin switching currents. Choose a 10V rated low ESR, X7R or X5R ceramic capacitor for best performance. A 4.7µF capacitor will be adequate for many applications. Place the capacitor close to the IC to minimize the trace length to the INTV CC pin and also to the IC ground.An internal current limit on the INTV CC output protects the L T3956 from excessive on-chip power dissipation. The INTV CC pin has its own undervoltage disable (UVLO) set to 4.1V (typical) to protect the internal MOSFET from excessive power dissipation caused by not being fully en-hanced. If the INTV CC pin drops below the UVLO threshold, the PWMOUT pin will be forced to 0V , the power switch turned off and the soft-start pin will be reset.If the input voltage, V IN , will not exceed 7V , then the INTV CC pin could be connected to the input supply. This action allows the L T3956 to operate from as low as 4.5V . Be aware that a small current (less than 12μA) will load the INTV CC in shutdown. Otherwise, the minimum operating V IN value is determined by the dropout voltage of the linear regulator and the 4.4V (4.1V typical) INTV CC undervoltage lockout threshold mentioned above.Programming the Turn-On and Turn-Off Thresholds With the EN/UVLO PinThe falling UVLO value can be accurately set by the resistor divider . A small 2.1µA pull-down current is active when EN/UVLO is below the falling threshold. The purpose of this current is to allow the user to program the rising hysteresis. The following equations should be used to determine the values of the resistors: V R R R IN FALLING ,.•=+122122V µA R V IN RISING IN FALLING,,.•=+211Figure 1LED Current ProgrammingThe LED current is programmed by placing an appropri-ate value current sense resistor , R LED , between the ISP and ISN pins. Typically, sensing of the current should be done at the top of the LED string. If this option is not available, then the current may be sensed at the bottom of the string, but take caution that the minimum ISN value does not fall below 3V , which is the lower limit of the LED current regulation function. The CTRL pin should be tied to a voltage higher than 1.2V to get the full-scale 250mV (typical) threshold across the sense resistor . The CTRL pin can also be used to dim the LED current to zero, although relative accuracy decreases with the decreasing voltage sense threshold. When the CTRL pin voltage is less than 1V , the LED current is: I V mV R LED CTRL LED =−1004•When the CTRL pin voltage is between 1V and 1.2V the LED current varies with CTRL, but departs from the previous equation by an increasing amount as the CTRL voltage increases. Ultimately, above CTRL = 1.2V , the LED current no longer varies with CTRL. At CTRL = 1.1V , the actual value of I LED is ~98% of the equation’s estimate. When V CTRL is higher than 1.2V , the LED current is regu-lated to: I mV R LED LED=250The CTRL pin should not be left open (tie to V REF if not used). The CTRL pin can also be used in conjunction with a thermistor to provide overtemperature protection for the LED load, or with a resistor divider to V IN to reduce output power and switching current when V IN is low. The presence of a time varying differential voltage signal (ripple) across ISP and ISN at the switching frequency is expected. The amplitude of this signal is increased by high LED load current, low switching frequency and/or a smaller value output filter capacitor . Some level of ripple signal is acceptable: the compensation capacitor on the V C pin filters the signal so the average difference between ISP and ISN is regulated to the user-programmed value.

December 2007 Rev 11/8STTH8S06Turbo 2 ultrafast high voltage rectifierFeatures■Ultrafast recovery■Low reverse recovery current■Reduces losses in diode and switching transistor■Low thermal resistance ■Higher frequency operation ■Insulated TO-220FPAC version –Insulation voltage = 1500 V rms –Package capacitance = 12 pFDescriptionST's STTH8S06 is a state of the art ultrafast recovery diode. By the use of 600 V Pt doping planar technology , this diode will out-perform the power factor corrections circuits operating in hardswitching conditions. The extremely low reverse recovery current of the STTH8S06,reduces significantly the switching power losses of the MOSFET and thus increases the efficiency of the application. This leads designers to reduce the size of their heatsinks.This device is also intended for applications in power supplies and power conversions systems, motor drive, and other power switching applications.Table 1.Device summaryI F(AV)8 A V RRM 600 V I RM (typ.) 4.4 A T j (max)175 °C V F (typ) 1.5 V t rr (typ)12 nsCharacteristics STTH8S062/81 CharacteristicsTo evaluate the maximum conduction losses use the following equation:P = 1.20 x I F(AV) + 0.087 I F 2(RMS)Table 2.Absolute ratings (limiting values)Symbol ParameterValue Unit V RRM Repetitive peak reverse voltage 600V I F(AV)Average forward current8A I FSM Surge non repetitive forward current t p = 10 ms60A T stg Storage temperature range-65 to + 175°C T jMaximum operating junction temperature175°CTable 3.Thermal parameterSymbol ParameterMaximumUnit R th(j-c)Junction to caseTO-220AC 3.0°C/WTO220FP AC5.5Table 4.Static electrical characteristicsSymbol ParameterTest conditions Min.TypMax.Unit I RReverse leakage currentT j = 25 °C V R = 600 V20µAT j = 125 °C 25200V FForward voltage dropT j = 25 °C I F = 8 A3.4VT j = 125 °C1.51.9Table 5.Dynamic electrical characteristicsSymbol ParameterTest conditionsMin.Typ Max.Unit t rr Reverse recovery time I F = 1 A, dI F /dt = - 200 A/µs, V R = 30 V1218ns I RM Reverse current T j = 25 °CI F = 8 A, dI F /dt = - 200 A/µs, V R = 200 V 1.6 2.2A S factor Softness factor1-Q rr Reverse recovery charges 17nC I RM Reverse current T j = 125 °CI F = 8 A, dI F /dt = - 200 A/µs, V R = 200 V4.4 6.0A S factor Softness factor0.3-Q rrReverse recovery charges90nCSTTH8S06Characteristics3/8Figure 1.Forward voltage drop versus forward currentFigure 2.Relative variation of thermalimpedance junction to case versusFigure 3.Relative variation of thermal impedance junction to case versus Figure 4.Peak reverse recovery current versus dI F /dt (typical values)Tδ=tp/TtpCharacteristics STTH8S06 Figure 5.Reverse recovery time versus dI F/dt Figure 6.Reverse recovery charges versus4/8STTH8S06Package information5/82 Package information●Epoxy meets UL94, V0●Cooling method: by conduction (C)●Recommended torque value: 0.4 to 0.6 N·mIn order to meet environmental requirements, ST (also) offers these devices in ECOPACK®packages.

UCC1946UCC2946UCC3946SLUS247B - FEBRUARY 2000FEATURES•Fully Programmable Reset Threshold •Fully Programmable Reset Period •Fully Programmable Watchdog Period •2% Accurate Reset Threshold •VDD Can Go as Low as 2V •18µA Maximum IDD •Reset Valid Down to 1VMicroprocessor Supervisor with Watchdog TimerBLOCK DIAGRAMDESCRIPTIONThe UCC3946is designed to provide accurate microprocessor supervi-sion,including reset and watchdog functions.During power up,the IC asserts a reset signal RES with VDD as low as 1V .The reset signal re-mains asserted until the VDD voltage rises and remains above the re-set threshold for the reset period.Both reset threshold and reset period are programmable by the user.The IC is also resistant to glitches on the VDD line.Once RES has been deasserted,any drops below the threshold voltage need to be of certain time duration and voltage mag-nitude to generate a reset signal.These values are shown in Figure 1.An I/O line of the microprocessor may be tied to the watchdog input (WDI)for watchdog functions.If the I/O line is not toggled within a set watchdog period,programmable by the user,WDO will be asserted.The watchdog function will be disabled during reset conditions.The UCC3946is available in 8-pin SOIC(D),8-pin DIP (N or J)and 8-pin TSSOP(PW) packages to optimize board space.查询UCC1946供应商ELECTRICAL CHARACTERISTICS:Unless otherwise

UCC3946supervisory circuit provides accurate re-set and watchdog functions for a variety of microproces-sor applications.The reset circuit prevents the microprocessor from executing code during undervoltage conditions,typically during power-up and power-down.In order to prevent erratic operation in the presence of noise,voltage “glitches”whose voltage amplitude and time duration are less than the values specified in Fig.1are ignored.The watchdog circuit monitors the microprocessor’s ac-tivity,if the microprocessor does not toggle WDI during the programmable watchdog period WDO will go low,alerting the microprocessor’s interrupt of a fault.The WDO pin is typically connected to the non-maskable in-put of the microprocessor so that an error recovery rou-tine can be executed.APPLICATION INFORMATIONFigure 1.Overdrive voltage vs.delay to output low on RESB.Slew rate:–1V/mS;monitored voltage =V DD .GND:Ground reference for the IC.RES:This pin is high only if the voltage on the RTH has risen above 1.235V .Once RTH rises above the threshold,this pin remains low for the reset period.This pin will also go low and remain low if the RTH voltage dips below 1.235V for an amount of time determined by Figure 1.RTH:This input compares its voltage to an internal 1.25V reference.By using external resistors,a user can pro-gram any reset threshold he wishes to achieve.RP:This pin allows the user to program the reset period by adjusting an external capacitor.VDD:Supply voltage for the IC.WDI:This pin is the input to the watchdog timer.If this pin is not toggled or strobed within the watchdog period,WDO is asserted.WDO:This pin is the watchdog output.This pin will be asserted low if the WDI pin is not strobed or toggled within the watchdog period.WP:This pin allows the user toprogram the watchdog period by adjusting an external capacitor.PIN DESCRIPTIONSFigure 2.Typical RTH threshold vs.temperature.Figure 3.Typical IDD vs VDD.Programming the Reset Voltage and Reset Period The UCC3946allows the reset trip voltage to be pro-grammed with two external resistors.In most applications VDD is monitored by the reset circuit,however,the de-sign allows voltages other than VDD to be monitored.Referring to Fig.4,the voltage below which reset will be asserted is determined by:V =1.235•R1+R2R2RESET In order to keep quiescent currents low,resistor values in the megaohm range can be used for R1and R2.A man-ual reset can be easily implemented by connecting a mo-mentary push switch in parallel with R2.RES is guaranteed to be low with VDD voltages as low as 1V .Once VDD rises above the programmed threshold,RES remains low for the reset period defined by:T C RP RP=•3125.where T RP is time in milliseconds and C RP is capacitance in nanofarads.C RP is charged with a precision current source of 400nA,a high quality,low leakage capacitor (such as an NPO ceramic)should be used to maintain timing tolerances.Fig.5illustrates the voltage levels and timings associated with the reset circuit.Programming the Watchdog PeriodThe watchdog period is programmed with C WP as fol-lows:T C WP WP=•25where T WP is in milliseconds and C WP is in nanofarads.A high quality,low leakage capacitor should be used for C WP .The watchdog input WDI must be toggled with a high/low or low/high transition within the watchdog period to prevent WDO from assuming a logic level low.WDO will maintain the low logic level until WDI is toggled or RES is asserted.If at any time RES is asserted,WDO will assume a high logic state and the watchdog period will be reinitiated.Fig.6illustrates the timings associated with the watchdog circuit.Figure 4.Typical application diagram.Connecting WDO to RESIn order to provide design flexibility,the reset and watch-dog circuits in the UCC3946have separate outputs.Each output will independently drive high or low,depending on circuit conditions explained previously.In some applications,it may be desirable for either the RES or WDO to reset the microprocessor.This can be done by connecting WDO to RES.If the pins try to drive to different output levels,the low output level will domi-nate.Additional current will flow from VDD to GND during these states.If the application cannot support additional current(during fault conditions),RES and WDO can be connected to the inputs of an OR gate whose output is connected to the microprocessor’s reset yout ConsiderationsA0.1µF capacitor connected from V DD to GND is recom-mended to decouple the UCC3946from switching tran-sients on the V DD supply rail.Since RP and WP are precision current sources,capaci-tors C RP and C WP should be connected to these pins with minimal trace length to reduce board capacitance. Care should be taken to route any traces with high volt-age potential or high speed digital signals away from these capacitors.Resistors R1and R2generally have a high ohmic value, traces associated with these parts should be kept short in order to prevent any transient producing signals from coupling into the high impedance RTH pin.Figure 5.Reset circuit timings.Figure 6.Watchdog circuit timings.
