LM1577/LM2577SeriesSIMPLE SWITCHER ®Step-Up Voltage RegulatorGeneral DescriptionThe LM1577/LM2577are monolithic integrated circuits that provide all of the power and control functions for step-up (boost),flyback,and forward converter switching regulators.The device is available in three different output voltage ver-sions:12V,15V,and adjustable.Requiring a minimum number of external components,these regulators are cost effective,and simple to use.Listed in this data sheet are a family of standard inductors and flyback transformers designed to work with these switching regula-tors.Included on the chip is a 3.0A NPN switch and its associated protection circuitry,consisting of current and thermal limiting,and undervoltage lockout.Other features include a 52kHz fixed-frequency oscillator that requires no external compo-nents,a soft start mode to reduce in-rush current during start-up,and current mode control for improved rejection of input voltage and output load transients.Featuresn Requires few external componentsn NPN output switches 3.0A,can stand off 65V n Wide input voltage range:3.5V to 40VnCurrent-mode operation for improved transient response,line regulation,and current limit n 52kHz internal oscillatorn Soft-start function reduces in-rush current during start-up n Output switch protected by current limit,under-voltage lockout,and thermal shutdownTypical Applicationsn Simple boost regulatorn Flyback and forward regulators n Multiple-output regulatorTypical ApplicationOrdering InformationTemperature Range Package TypeOutput

as a Step-Up Regulator.This is a switching regulator used for producing an output voltage greater than the input supply voltage.The LM1577-12/LM2577-12and LM1577-15/LM2577-15can also be used for step-up regulators with 12V or 15V outputs (respectively),by tying the feedback pin di-rectly to the regulator output.A basic explanation of how it works is as follows.The LM1577/LM2577turns its output switch on and off at a fre-quency of 52kHz,and this creates energy in the inductor (L).When the NPN switch turns on,the inductor current charges up at a rate of V IN /L,storing current in the inductor.When the switch turns off,the lower end of the inductor flies above V IN ,discharging its current through diode (D)into the output ca-pacitor (C OUT )at a rate of (V OUT −V IN )/L.Thus,energy stored in the inductor during the switch on time is transferred to the output during the switch off time.The output voltage is controlled by the amount of energy transferred which,in turn,is controlled by modulating the peak inductor current.This is done by feeding back a portion of the output voltage to the error amp,which amplifies the difference between the feed-back voltage and a 1.230V reference.The error amp output voltage is compared to a voltage proportional to the switch current (i.e.,inductor current during the switch on time).The comparator terminates the switch on time when the two voltages are equal,thereby controlling the peak switch cur-rent to maintain a constant output voltage.Voltage and current waveforms for this circuit are shown in Figure 5,and formulas for calculating them are given in Fig-ure 6.STEP-UP REGULATOR DESIGN PROCEDUREThe following design procedure can be used to select the ap-propriate external components for the circuit in Figure 4,based on these system requirements.Given:V IN (min)=Minimum input supply voltage V OUT =Regulated output voltageI LOAD(max)=Maximum output load currentBefore proceeding any further,determine if the LM1577/LM2577can provide these values of V OUT and I LOAD(max)when operating with the minimum value of V IN .The upper limits for V OUT and I LOAD(max)are given by the following equations.V OUT ≤60V andV OUT ≤10x V IN(min)These limits must be greater than or equal to the values specified in this application.1.Inductor Selection (L)A.Voltage Options:1.For 12V or 15V outputDS011468-11FIGURE 5.Step-Up Regulator WaveformsDuty Cycle DAverage Inductor CurrentI IND(AVE)Application Hints(Continued)From Figure7(for12V output)or Figure8(for15Voutput),identify inductor code for region indicated byV IN(min)and I LOAD(max).The shaded region indicatesconditions for which the LM1577/LM2577output switchwould be operating beyond its switch current rating.Theminimum operating voltage for the LM1577/LM2577is3.5V.From here,proceed to step C.2.For Adjustable versionPreliminary calculations:The inductor selection is based on the calculation of thefollowing three parameters:D(max),the maximum switch duty cycle(0≤D≤0.9):where V F=0.5V for Schottky diodes and0.8V for fast recov-ery diodes(typically);E•T,the product of volts x time that charges the inductor:I IND,DC,the average inductor current under full load;B.Identify Inductor Value:1.From Figure9,identify the inductor code for the re-gion indicated by the intersection of E•T and I IND,DC.This code gives the inductor value in microhenries.TheL or H prefix signifies whether the inductor is rated for amaximum E•T of90V•µs(L)or250V•µs(H).2.If D<0.85,go on to step C.If D≥0.85,then calcu-late the minimum inductance needed to ensure theswitching regulator’s stability:If L MIN is smaller than the inductor value found in step B1,goon to step C.Otherwise,the inductor value found in step B1is too low;an appropriate inductor code should be obtainedfrom the graph as follows:1.Find the lowest value inductor that is greater than L MIN.2.Find where E•T intersects this inductor value to determineif it has an L or H prefix.If E•T intersects both the L and H re-gions,select the inductor with an H prefix.DS011468-27FIGURE7.LM2577-12Inductor Selection GuideDS011468-28FIGURE8.LM2577-15Inductor Selection Guide 14Application Hints(Continued)C.Select an inductor from the table of Figure10whichcross-references the inductor codes to the part numbers of three different plete specifica-tions for these inductors are available from the respec-tive manufacturers.The inductors listed in this table have the following characteristics:AIE:ferrite,pot-core inductors;Benefits of this type are low electro-magnetic interference(EMI),small physical size,and very low power dissipation(core loss).Be careful not to operate these inductors too far beyond their maximum ratings for E•T and peak current,as this will saturate the core.Pulse:powdered iron,toroid core inductors;Benefits are low EMI and ability to withstand E•T and peak current above rated value better than ferrite cores.Renco:ferrite,bobbin-core inductors;Benefits are low cost and best ability to withstand E•T and peak current above rated value.Be aware that these inductors gener-ate more EMI than the other types,and this may inter-fere with signals sensitive to noise.DS011468-12Note:These charts assume that the inductor ripple current inductor is approximately20%to30%of the average inductor current(when the regulator is underfull load).Greater ripple current causes higher peak switch currents and greater output ripple voltage;lower ripple current is achieved with larger-valueinductors.The factor of20to30%is chosen as a convenient balance between the two extremes.FIGURE9.LM1577-ADJ/LM2577-ADJ Inductor Selection Graph15Application Hints(Continued)pensation Network(R C,C C)and Output Capacitor(C OUT)SelectionR C and C C form a pole-zero compensation network that sta-bilizes the regulator.The values of R C and C C are mainly de-pendant on the regulator voltage gain,I LOAD(max),L andC OUT.The following procedure calculates values for R C,C C,and C OUT that ensure regulator stability.Be aware that thisprocedure doesn’t necessarily result in R C and C C that pro-vide optimum compensation.In order to guarantee optimumcompensation,one of the standard procedures for testingloop stability must be used,such as measuring V OUT tran-sient response when pulsing I LOAD(see Figure15).A.First,calculate the maximum value for R C.Select a resistor less than or equal to this value,and itshould also be no greater than3kΩ.B.Calculate the minimum value for C OUT using the followingtwo equations.The larger of these two values is the minimum value that en-sures stability.C.Calculate the minimum value of C C.The compensation capacitor is also part of the soft start cir-cuitry.When power to the regulator is turned on,the switchduty cycle is allowed to rise at a rate controlled by this ca-pacitor(with no control on the duty cycle,it would immedi-ately rise to90%,drawing huge currents from the inputpower supply).In order to operate properly,the soft start cir-cuit requires C C≥0.22µF.The value of the output filter capacitor is normally largeenough to require the use of aluminum electrolytic capaci-tors.Figure11lists several different types that are recom-mended for switching regulators,and the following param-eters are used to select the proper capacitor.Working Voltage(WVDC):Choose a capacitor with a work-ing voltage at least20%higher than the regulator output volt-age.Ripple Current:This is the maximum RMS value of currentthat charges the capacitor during each switching cycle.Forstep-up and flyback regulators,the formula for ripple currentisChoose a capacitor that is rated at least50%higher than thisvalue at52kHz.Equivalent Series Resistance(ESR):This is the primarycause of output ripple voltage,and it also affects the valuesof R C and C C needed to stabilize the regulator.As a result,the preceding calculations for C C and R C are only valid ifESR doesn’t exceed the maximum value specified by the fol-lowing equations.Select a capacitor with ESR,at52kHz,that is less than orequal to the lower value calculated.Most electrolytic capaci-tors specify ESR at120Hz which is15%to30%higher thanat52kHz.Also,be aware that ESR increases by a factor of2when operating at−20˚C.In general,low values of ESR are achieved by using largevalue capacitors(C≥470µF),and capacitors with highWVDC,or by paralleling smaller-value capacitors.Inductor Manufacturer’s Part NumberCode Schott Pulse

R2GNDU1源自开路保护的设置要注意几点： 1) 为方便设计，需使电阻由Rst21和Rst22相 等，即Rst21=Rst22，以达到平均分摊采样电压的 作用， 用于过压保护OVP值的设定。 Rst21和Rst22 的取值在150K欧姆~400K欧姆之间。如果需要支 持的母线电压偏低，则电阻Rst21和Rst22取值要 小；反之，则可以大一些，以提高系统效率。 2) 受分压电阻串R1， R2的精度影响， 以及芯 片内部参考电平的精度影响，公式（6）计算得到 的OVP阈值与实际的OVP阈值有一定的误差。准 确的OVP值可以通过调节R2的阻值来达到。OVP 值偏低，应该减小R2阻值；反之，则应加大R2的 阻值。建议R2初值取4.7K欧姆左右，用公式（6） 来确定R1的阻值，然后微调R2来精确确定OVP 值。 3) 建议将开路保护阈值设置在系统最大的

Sinchronous Rectifier that eliminates the need for an external catch diode,and allows regulation even when the input is greater than the output.Unlike others step-up DC-DC converters the ST777/778/779’s Sinchronous Rectifier turns off in the shutdown mode,fully disconnecting the output from the source.This eliminates the current drain associated with conventional step-up converters when off or in shutdown.Supply current is 270µA under no load and only 20µA in stand by mode.ST777/778/779LOW VOLTAGE INPUT,3-3.3V/5V/ADJUSTABLE OUTPUT DC-DC CONVERTER WITH SYNCHRONOUS RECTIFIERV INV

Current0.1µAST777/778/7794/11TYPICAL APPLICATION CIRCUITAPPLICATIONS INFORMATIONR1and R2must be placed only in ST779applications to set the output voltage according to the following equation:V OUT =(1.23)[(R1+R2)/R2]and to simplify the resistor selection:R1=R2[(V OUT /1.23)-1]It is possible to use a wide range of values for R2(10K Ωto 50K Ω)with no significant loss of accuracy thanks to the very low FB input current.To have 1%error,the current through R2must be at least 100times FB’s bias current.When large values are used for the feedback resistors (R1>50K Ω),stray output impedance at FB can incidentally add "lag"to the feedback response,destabilizing the regulator and creating a larger ripple at the output.Lead lengths and circuit board traces at the FB node should be kept pensate the loop by adding a "lead"compensation capacitor (C3,100pF to 1nF)in parallel with R1.The typical value of the L1inductor is 22µH,enough for most applications.However,are also suitable values ranging from 10µF to 47µF with a saturation rating equal to or greater than the peak switch -current limit.Efficiency will be reduced if the inductor works near its saturation limit,while will be maximized using an inductor with a low DC resistance,preferably under 0.2Ω.Connecting ILIM to V IN the maximum LX current limit (1A)is set.If this maximum value is not required is possible to reduce it connecting a resistor between ILIM and V IN (See Figure 16to choose the right value).The current limit value is misured when the switch current through the inductor begins to flatten and does’nt coincide with the max short circuit current.Even if the device is designed to tolerate a short circuit without any damage,it is strictly recommended to avoid a continuos and durable short circuit of the output to GND.To achieve the best performances from switching power supply topology,particular care to layout drawing is needed,in order to minimize EMI and obtain low noise.Moreover,jitter free operation ensures the full device functionality.Wire lengths must be minimized,filter and by-pass capacitors must be low ESR type,placed as close as possible to the integrated circuit.Solder AGND and PGND pins directly to a ground plane.ST777/778/7795/11TYPICAL CHARACTERISTICS (unless otherwise specified T j =25°C,C I =22µF,C O =100µF)Figure 1:Output Voltage vs TemperatureFigure 2:Output Voltage
