12Application SectionLMV341/342/344The LMV341/342/344family of amplifiers features low volt-age,low power,and rail-to-rail output operational amplifiers designed for low voltage portable applications.The family is designed using all CMOS technology.This results in an ultra low input bias current.The LMV341has a shutdown option, which can be used in portable devices to increase battery life.A simplified schematic of the LMV341/342/344family of amplifiers is shown in Figure1.The PMOS input differential pair allows the input to include ground.The output of this differential pair is connected to the Class AB turnaround stage.This Class AB turnaround has a lower quiescent current,compared to regular turnaround stages.This results in lower offset,noise,and power dissipation,while slew rate equals that of a conventional turnaround stage.The output of the Class AB turnaround stage provides gate voltage to the complementary common-source transistors at the output stage.These transistors enable the device to have rail-to-rail output.CLASS AB TURNAROUND STAGE AMPLIFIERThis patented folded cascode stage has a combined class AB amplifier stage,which replaces the conventional folded cascode stage.Therefore,the class AB folded cascode stage runs at a much lower quiescent current compared to conventional folded cascode stages.This results in signifi-cantly smaller offset and noise contributions.The reduced offset and noise contributions in turn reduce the offset volt-age level and the voltage noise level at the input of the LMV341/342/344.Also the lower quiescent current results in a high open-loop gain for the amplifier.The lower quiescent current does not affect the slew rate of the amplifier nor its ability to handle the total current swing coming from the input stage.The input voltage noise of the device at low frequencies, below1kHz,is slightly higher than devices with a BJT input stage;However the PMOS input stage results in a much lower input bias current and the input voltage noise drops at frequencies above1kHz.SAMPLE AND HOLD CIRCUITThe lower input bias current of the LMV341results in a very high input impedance.The output impedance when the de-vice is in shutdown mode is quite high.These high imped-ances,along with the ability of the shutdown pin to be derived from a separate power source,make LMV341a good choice for sample and hold circuits.The sample clock should be connected to the shutdown pin of the amplifier to rapidly turn the device on or off.Figure2shows the schematic of a simple sample and hold circuit.When the sample clock is high the first amplifier is in normal operation mode and the second amplifier acts as a buffer.The capacitor,which appears as a load on the first amplifier,will be charging at this time.The voltage across the capacitor is that of the non-inverting input of the first amplifier since it is connected as a voltage-follower.When the sample clock is low the first amplifier is shut off,bringing the output impedance to a high value.The high impedance of this output,along with the very high impedance on the input of the second amplifier,prevents the capacitor from discharg-ing.There is very little voltage droop while the first amplifier is in shutdown mode.The second amplifier,which is still in normal operation mode and is connected as a voltage fol-lower,also provides the voltage sampled on the capacitor at its output.SHUTDOWN FEATUREThe LMV341is capable of being turned off in order to conserve power and increase battery life in portable devices. Once in shutdown mode the supply current is drastically reduced,1µA maximum,and the output will be"tri-stated." The device will be disabled when the shutdown pin voltage is pulled low.The shutdown pin should never be left uncon-nected.Leaving the pin floating will result in an undefined operation mode and the device may oscillate between shut-down and active modes.The LMV341typically turns on2.8µs after the shutdown voltage is pulled high.The device turns off in less than400ns after shutdown voltage is pulled low.Figure3and Figure4 show the turn-on and turn-off time of the LMV341,respec-tively.In order to reduce the effect of the capacitance added to the circuit by the scope probe,in the turn-off time circuit a resistive load of600Ωis added.Figure5and Figure6show the test circuits used to obtain the two plots.20030453 FIGURE1.Simplified Schematic20030444FIGURE2.Sample and Hold CircuitLMV341/LMV342/LMV34413Application Section(Continued)LOW INPUT BIAS CURRENTThe LMV341/LMV342/LMV344Amplifiers have a PMOS in-put stage.As a result,they will have a much lower input bias current than devices with BJT input stages.This feature makes these devices ideal for sensor circuits.A typical curve of the input bias current of the LMV341is shown in Figure 7.20030440FIGURE 3.Turn-on Time20030439FIGURE 4.Turn-off Time20030442FIGURE 5.Turn-on Time20030443FIGURE 6.Turn-off Time20030447FIGURE 7.Input Bias Current vs.V CML M V 341/L M V 342/L M V 344 14Physical Dimensionsinches (millimeters)unless otherwise noted6-Pin SC70NS Package Number MAA06A8-Pin MSOPNS Package Number MUA08ALMV341/LMV342/LMV34415Physical Dimensionsinches (millimeters)unless otherwise noted (Continued)8-Pin SOICNS Package Number M08A14-Pin TSSOPNS Package Number MTC14L M V 341/L M V 342/L M V 344 16Physical Dimensionsinches (millimeters)unless otherwise noted (Continued)14-Pin SOICNS Package Number M14ALIFE SUPPORT POLICYNATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL COUNSEL OF NATIONAL SEMICONDUCTOR CORPORATION.As used herein:1.Life support devices or systems are devices or systems which,(a)are intended for surgical implant into the body,or (b)support or sustain life,and whose failure to perform when properly used in accordance with instructions for use provided in the labeling,can be reasonably expected to result in a significant injury to the user.2.A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system,or to affect its safety or effectiveness.National Semiconductor Americas Customer Support CenterEmail:new.feedback@ Tel:1-800-272-9959National SemiconductorEurope Customer Support CenterFax:+49(0)180-5308586Email:europe.support@Deutsch Tel:+49(0)6995086208English Tel:+44(0)8702402171Français Tel:+33(0)141918790National Semiconductor Asia Pacific Customer Support Center Fax:+65-62504466Email:ap.support@ Tel:+65-62544466National SemiconductorJapan Customer Support Center Fax:81-3-5639-7507Email:jpn.feedback@ Tel:81-3-5639-7560LMV341/LMV342/LMV344Single with Shutdown/Dual/Quad General Purpose,2.7V,Rail-to-Rail Output,125˚C,Operational AmplifiersNational does not assume any responsibility for use of any circuitry described,no circuit patent licenses are implied and National reserves the right at any time without notice to change said circuitry and specifications.。

脉宽调制开关电源控制IC汇总

脉宽调制开关电源控制IC汇总

脉宽调制开关电源控制IC开关电源这个名字我们大家都不会感到很陌生。

常见的计算系统电源录象机、电视机电源都使用了这种电源技术。

但是常常会觉得这种电源技术好象很复杂根本不可能自已制作此类电源,当然早期的开关电源控制部份集成电路使得开关电源的外围变得如此简单以至于简单过一线性稳压电源。

这里介绍的是 sgs T开关电源这个名字我们大家都不会感到很陌生。

常见的计算系统电源录象机、电视机电源都使用了这种电源技术。

但是常常会觉得这种电源技术好象很复杂根本不可能自已制作此类电源,当然早期的开关电源控制部份集成电路使得开关电源的外围变得如此简单以至于简单过一线性稳压电源。

这里介绍的是 sgs Thomson 公司生产的新型系列集成稳压IC:UCX84X 之中的 UC1842 与系列中的其它 IC 相比,它们的内部电路结构基本上是一致的,只在某些参数如工作环境温度内部基准电压精度,最大占空比系数等方面有所区别所以原则上此类IC的外围电路是可以通用的。

UC1842 为脉冲调制 (PCM) 的开关电源控制 IC。

其封装为 8 脚,可谓简洁说明了。

其内部方框图如下:现介绍各脚功能:1脚为内部误差放大器输出端;2脚为误差放大输入端;1与2 脚之间接有反馈网络以确定反馈放大器增益与频响;2脚输入的反馈电压将与基准2.5V电压比较以产生控制电压;3脚为电流传感器输入引脚,当由电流传感器送来的电压超过1V时及当开关管过流时调宽脉冲就停止输出这样就保护了开关管防止意外损坏。

4脚为接定时电阻电容端口。

由外接的电容电阻决定内部振荡器振荡频率:f=1.8/Rt*Ct;5脚为接地端;6脚为输出调宽脉冲端口,输出的脉冲是推动后的开关管。

其驱动很强,达到 +1A 或 -1A 。

在负载叫容为 1000pF 时上升下降时间仅为 500S,所以很适合于推动VMOS管7脚为电源电压输入端,供电电压可在10V-30V,当电压低于10V时停止工作,工作电流 15mA,功耗是非常小的,因此工作稳定。

UC3842芯片资料各管脚功能简介如下。

---1脚COMP是内部误差放大器的输出端,通常此脚与2脚之间接有反馈网络,以确定误差放大器的增益和频响。

---2脚FEED BACK是反馈电压输入端,此脚与内部误差放大器同向输入端的基准电压(一般为+2.5V)进行比较,产生控制电压,控制脉冲的宽度。

---3脚ISENSE是电流传感端。

在外围电路中,在功率开关管(如VMos管)的源极串接一个小阻值的取样电阻,将脉冲变压器的电流转换成电压,此电压送入3脚,控制脉宽。

此外,当电源电压异常时,功率开关管的电流增大,当取样电阻上的电压超过1V 时,UC3842就停止输出,有效地保护了功率开关管。

---4脚RT/CT是定时端。

锯齿波振荡器外接定时电容C和定时电阻R的公共端。

5脚GND是接地。

6脚OUT是输出端,此脚为图滕柱式输出,驱动能力是±lA。

这种图腾柱结构对被驱动的功率管的关断有利,因为当三极管VTl截止时,VT2导通,为功率管关断时提供了低阻抗的反向抽取电流回路,加速功率管的关断。

7脚Vcc是电源。

当供电电压低于+16V时,UC3824不工作,此时耗电在1mA以下。

输入电压可以通过一个大阻值电阻从高压降压获得。

芯片工作后,输入电压可在+10~+30V之间波动,低于+10V停止工作。

工作时耗电约为15mA,此电流可通过反馈电阻提供。

8脚VREF是基准电压输出,可输出精确的+5V基准电压,电流可达50mA。

UV3842的电压调整率可达0.01%,工作频率为500kHz,启动电流小于1mA,输入电压为10~30V,基准电压为4.9~5.1V,工作温度为0~70℃,输出电流为1A。

Thermal shutdown engages at T J =165°C (typical) and disengages at T J =140°C (typical).Note 4:Junction-to-ambient thermal resistance is highly board-layout dependent. The numbers listed in the table are given for a reference layout wherein the 20L TSSOP EP package has its DAP pad populated with 9 vias. In applications where high maximum power dissipation exists, namely driving a large MosFET at high switching frequency from a high input voltage, special care must be paid to thermal dissipation issues during board design. In high-power dissipation applications, the maximum ambient temperature may have to be derated. Maximum ambient temperature (T A-MAX ) is dependent on the maximum operating junction temperature (T J-MAX-OP = 125°C), the maximum power dissipation of the device in the application (P D-MAX ), and the junction-to ambient thermal resistance of the package in the application (θJA ), as given by the following equation: T A-MAX = T J-MAX-OP – (θJA × P D-MAX ). In most applications there is little need for the full power dissipation capability of this advanced package. Under these circumstances, no vias would be required and the thermal resistances would be 104 °C/W for the 20L TSSOP EP. It is possible to conservatively interpolate between the full via count thermal resistance and the no via count thermal resistance with a straight line to get a thermal resistance for any number of vias in between these two limits.Note 5:Refer to National’s packaging website for more detailed information and mounting techniques. /analog/packaging/Note 6:Human Body Model, applicable std.

The controller has wide input voltage range allowing for regulation of a variety of LED loads. The high-side differential current sense, with low adjustable threshold voltage, provides an excellent method for regulating output current while maintaining high system efficiency. The LM3424 uses peak current mode control providing good noise immunity and an inherent cycle-by-cycle current limit. The adjustable current sense threshold provides the capability toamplitude (analog) dim the LED current and the thermal fold-back circuitry allows for precise temperature management ofthe LEDs. Tthe output enable/disable function coupled withan internal dimming drive circuit provides high speed PWMdimming through the use of an external MosFET placed at theLED load. When designing, the maximum attainable LED cur-rent is not internally limited because the LM3424 is a con-troller. Instead it is a function of the system operating point,component choices, and switching frequency allowing theLM3424 to easily provide constant currents up to 5A. Thissimple controller contains all the features necessary to im-plement a high efficiency versatile LED driver.LM342430085798FIGURE 1. Ideal CCM Regulator Inductor Current iL(t)CURRENT REGULATORSCurrent regulators can be designed to accomplish three basicfunctions: buck, boost, and buck-boost. All three topologiesin their most basic form contain a main switching MosFET, arecirculating diode, an inductor and capacitors. The LM3424is designed to drive a ground referenced NFET which is per-fect for a standard boost regulator. Buck and buck-boostregulators, on the other hand, usually have a high-side switch.When driving an LED load, a ground referenced load is oftennot necessary, therefore a ground referenced switch can beused to drive a floating load instead. The LM3424 can thenbe used to drive all three basic topologies as shown in theBasic Topology Schematics section. Other topologies suchas the SEPIC and flyback converter (both derivatives of thebuck-boost) can be implemented as well.Looking at the buck-boost design, the basic operation of acurrent regulator can be analyzed. During the time that theNFET (Q1) is turned on (tON), the input voltage source storesenergy in the inductor (L1) while the output capacitor (CO)provides energy to the LED load. When Q1 is turned off(tOFF), the re-circulating diode (D1) becomes forward biasedand L1 provides energy to both COand the LED load. Figure1 shows the inductor current (iL(t)) waveform for a regulatoroperating in CCM.The average output LED current (ILED) is proportional to theaverage inductor current (IL) , therefore if ILis tightly con-trolled, ILEDwill be well regulated. As the system changesinput voltage or output voltage, the ideal duty cycle (D) is var-ied to regulate ILand ultimately ILED. For any current regulator,D is a function of the conversion ratio:BuckBoostBuck-boostPEAK CURRENT MODE CONTROLPeak current mode control is used by the LM3424 to regulatethe average LED current through an array of HBLEDs. Thismethod of control uses a series resistor in the LED path tosense LED current and can use either a series resistor in theMosFET path or the MosFET RDS-ONfor both cycle-by-cyclecurrent limit and input voltage feed forward. The controller hasa fixed switching frequency set by an internal programmableoscillator which means current mode instability can occur atduty cycles higher than 50%. To mitigate this standard prob-lem, an aritifical ramp is added to the control signal internally.The slope of this ramp is programmable to allow for a widerrange of component choices for a given design. A detailedexplanation of this control method is presented in the follow-ing sections.SWITCHING FREQUENCYThe switching frequency of the LM3424 is programmed usingan external resistor (RT) connected from the RT pin to GNDas shown in Figure 2.Alternatively, an external PWM signal can be applied to theRT pin through a filter (RFLTand CFLT) and an AC couplingcapacitor (CAC) to synchronize the part to an external clockas shown in Figure 2. If the external PWM signal is applied ata frequency higher than the base frequency set by the RTre-sistor, the internal oscillator is bypassed and the switchingfrequency becomes the synchronized frequency. The exter-nal synchronization signal should have a pulse width of100ns, an amplitude between 3V and 6V, and be AC coupledto the RT pin with a ceramic capacitor (CAC= 100pF). A10MHz RC filter (RFLT= 150Ω and C FLT = 100 pF) should beplaced between the PWM signal and CACto eliminate un-wanted high frequency noise from coupling into the RT pin.The switching frequency is defined:See the Typical Performance Characteristics section for a plotof RTvs. fSW.10LM342430085799FIGURE 2. Timing CircuitryAVERAGE LED CURRENTTo first understand how the LM3424 regulates LED current,the thermal foldback functionality will be ignored. Figure 3shows the physical implementation of the LED current sensecircuitry assuming the thermal foldback circuitry is a simplecurrent source which, for now, will be set to zero (ITF= 0A).The LM3424 uses an external current sense resistor (RSNS)placed in series with the LED load to convert the LED current(ILED) into a voltage (VSNS). The HSP and HSN pins are theinputs to the high-side sense amplifier which are forced to beequal potential (VHSP=VHSN) through negative feedback. Be-cause of this, the VSNSvoltage is forced across RHSPwhichgenerates a current that is summed with the thermal foldbackcurrent (ITF) to generate the signal current (ICSH) which flowsout of the CSH pin and through the RCSHresistor. The erroramplifier will regulate the CSH pin to 1.24V and assumingITF= 0A, ICSHcan be calculated:This means VSNSwill be regulated as follows:ILEDcan then be calculated:The selection of the three resistors (RSNS, RCSH, and RHSP) isnot arbitrary. For matching and noise performance, the sug-gested signal current ICSHis approximately 100 µA. Thiscurrent does not flow in the LEDs and will not affect either theoff-state LED current or the regulated LED current. ICSHcanbe above or below this value, but the high-side amplifier offsetcharacteristics may be affected slightly. In addition, to mini-mize the effect of the high-side amplifier voltage offset on LEDcurrent accuracy, the minimum VSNSis suggested to be50 mV. Finally, a resistor (RHSN= RHSP) should be placed inseries with the HSN pin to cancel out the effects of the inputbias current (~10 µA) of both inputs of the high-side senseamplifier.Note that he CSH pin can also be used as a low-side currentsense input regulated to 1.24V. The high-side sense amplifieris disabled if HSP and HSN are tied to GND.30085757FIGURE 3. LED Current Sense CircuitryLM3424300857a1FIGURE 4. Thermal Foldback CircuitryTHERMAL FOLDBACK / ANALOG DIMMINGThermal foldback is necessary in many applications due tothe extreme temperatures created in LED environments. Ingeneral, two functions are necessary: a temperature break-point (TBK) after which the nominal operating current needs tobe reduced, and a slope corresponding to the amount of LEDcurrent decrease per temperature increase as shown in Fig-ure 5. The LM3424 allows the user to program both thebreakpoint and slope of the thermal foldback profile.300857c2FIGURE 5. Ideal Thermal Foldback ProfileFoldback is accomplished by adding current (ITF) to the CSHsumming node. As more current is added, less current isneeded from the high side amplifier and correspondingly, theLED current is regulated to a lower value. The final tempera-ture (TEND) is reached when ITF= ICSHcausing no current tobe needed from the high-side amplifier, yielding ILED= 0A.Figure 4 shows how the thermal foldback circuitry is physicallyimplemented in the system. ITFis set by placing a differentialvoltage (VDIF= VTREF– VTSENSE) across TSENSE and TREF.VTREFcan be set with a simple resistor divider (RREF1andRREF2) supplied from the VSvoltage reference (typical 2.45V).VTSENSEis set with a temperature dependant voltage (as tem-perature increases, voltage should decrease).An NTC thermistor is the most cost effective device used tosense temperature. As the temperature of the thermistor in-creases, its resistance decreases (albeit non-linearly). Usu-ally, the NTC manufacturer's datasheet will detail theresistance-temperature characteristic of the thermistor. Thethermistor will have a different resistance (RNTC) at each tem-perature. The nominal resistance of an NTC is the resistancewhen the temperature is 25°C (R25) and in many datasheetsthis will be given a multiplier of 1. Then the resistance at ahigher temperature will have a multiplier less than 1 (i.e. R85multiplier is 0.161 therefore R85= 0.161 x R25). Given a de-sired TBKand TEND, the corresponding resistances at thosetemperatures (RNTC-BKand RNTC-END) can be found.Using the NTC method, a resistor divider from VScan be im-plemented with a resistor connected between VSandTSENSE and the NTC thermistor placed at the desired loca-tion and connected from TSENSE to GND. This will ensurethat the desired temperature-voltage characteristic occurs atTSENSE.If a linear decrease over the foldback range is necessary, aprecision temperature sensor such as the LM94022 can beused instead as shown in Figure 4. Either method can be usedto set VTSENSEaccording to the temperature. However, for therest of this datasheet, the NTC method will be used for thermalfoldback calculations.During operation, if VDIF< 0V, then the sensed temperatureis less than TBKand the differential sense amplifier will regu-late its output to zero forcing ITF= 0. This maintains thenominal LED current and no foldback is observed.At TBK, VDIF= 0V exactly and ITFis still zero. Looking at themanufacturer's datasheet for the NTC thermistor, RNTC-BKcanbe obtained for the desired TBKand the voltage relationshipat the breakpoint (VTSENSE-BK= VTREF) can be defined:A general rule of thumb is to set RREF1= RREF2simplifying thebreakpoint relationship to RBIAS= RNTC-BK.If VDIF> 0V (temperature is above TBK), then the amplifier willregulate its output equal to the input forcing VDIFacross theresistor (RGAIN) connected from TGAIN to GND. RGAINulti-mately sets the slope of the LED current decrease with re-spect to increasing temperature by changing ITF:LM3424If an analog temperature sensor such as the LM94022 isused, then RBIASand the NTC are not necessary andVTENSEwill be the direct voltage output of the sensor.Since the NTC is not usually local to the controller, a bypasscapacitor (CNTC) is suggested from TSENSE to GND. If a ca-pacitor is used at TSENSE, then a capacitor (CREF) of equalor greater value should be placed from TREF to GND in orderto ensure the controller does not start-up in foldback. Alter-natively, a smaller CREFcan be used to create a fade-upfunction at start-up (see Application Information section).Thermal foldback is simply analog dimming according to aspecific profile, therefore any method of controlling the differ-ential voltage between TREF and TSENSE can be use toanalog dim the LED current. The corresponding LED currentfor any VDIF> 0V is defined:The CSH pin can also be used to analog dim the LED currentby adjusting the current sense voltage (VSNS), similar to ther-mal foldback. There are several different methods to adjustVSNSusing the CSH pin:1.External variable resistance : Adjust a potentiometerplaced in series with RCSHto vary VSNS.2.External variable current source: Source current (0 µA toICSH) into the CSH pin to adjust VSNS.300857k3FIGURE 6. Analog Dimming CircuitryIn general, analog dimming applications require a lowerswitching frequency to minimize the effect of the leading edgeblanking circuit. As the LED current is reduced, the outputvoltage and the duty cycle decreases. Eventually, the mini-mum on-time is reached. The lower the switching frequency,the wider the linear dimming range. Figure 6 shows how bothCSH methods are physically implemented.Method 1 uses an external potentiometer in the CSH pathwhich is a simple addition to the existing circuitry. However,the LEDs cannot dim completely because there is alwayssome resistance causing signal current to flow. This methodis also susceptible to noise coupling at the CSH pin since thepotentiometer increases the size of the signal current loop.Method 2 provides a complete dimming range and betternoise performance, though it is more complex. Like thermalfoldback, it simply sources current into the CSH pin, decreas-ing the amount of signal current that is necessary. Thismethod consists of a PNP current mirror and a bias networkconsisting of an NPN, 2 resistors and a potentiometer(RADJ), where RADJcontrols the amount of current sourcedinto the CSH pin. A higher resistance value will source morecurrent into the CSH pin causing less regulated signal currentthrough RHSP, effectively dimming the LEDs. Q7 and Q8should be a dual pair PNP for best matching and perfor-mance. The additional current (IADD) sourced into the CSH pincan be calculated:The corresponding ILEDfor a specific IADDis:THERMAL SHUTDOWNThe LM3424 includes thermal shutdown. If the die tempera-ture reaches approximately 165°C the device will shut down(GATE pin low), until it reaches approximately 140°C whereit turns on again.LM3424。
