LM3100SIMPLE SWITCHER ®Synchronous 1MHz 1.5A Step-Down Voltage RegulatorGeneral DescriptionThe LM3100Synchronously Rectified Buck Converter fea-tures all functions needed to implement a highly efficient,cost effective buck regulator capable of supplying 1.5A to loads with voltages as low as 0.8V.Dual 40V N-Channel synchronous MOSFET switches allow for low external com-ponent thus reducing complexity and minimizing board space.The LM3100is designed to work exceptionally well with ceramic and other very low ESR output capacitors.The Constant ON-Time (COT)regulation scheme requires no loop compensation,results in fast load transient response,and simplifies circuit implementation.Through the use of a unique design the regulator does not rely on output capacitor ESR for stability,as do most other COT regulators.The operating frequency remains nearly constant with line and load variations due to the inverse relationship between the input voltage and the on-time.The oprating frequency can be externally programmed up to 1MHz.Protection features include V CC under-voltage lockout,thermal shutdown and gate drive under-voltage lockout.The part is available in a thermally

effective,efficient buck power converter capable of supplying 1.5A to a load.This voltage regulator contains Dual 40V N-Channel buck syn-chronous switches and is available in a thermally enhanced eTSSOP-20package.The Constant ON-Time (COT)regu-lation scheme requires no loop compensation,results in fast load transient response,and simplifies circuit implementa-tion.It will work correctly even with an all ceramic output capacitor network and does not rely on the output capacitor’s ESR for stability.The operating frequency remains constant with line and load variations due to the inverse relationship between the input voltage and the on-time.The valley cur-rent limit detection circuit,internally set at 1.9A,inhibits the high-side switch until the inductor current level subsides.Please refer to the functional block diagram with a typical application circuit.The LM3100can be applied in numerous applications and can operate efficiently from inputs as high as 36V.Protection features include:Thermal shutdown,V CC under-voltage lockout,gate drive under-voltage lockout.Hysteretic Control Circuit OverviewThe LM3100buck DC-DC regulator employs a control scheme in which the high-side switch on-time varies in-versely with the line voltage (V IN ).Control is based on a comparator and the one-shot on-timer,with the output volt-age feedback (FB)compared with an internal reference of 0.8V.If the FB level is below the reference the buck switch is turned on for a fixed time determined by the input voltage and a programming resistor (R ON ).Following the on-time,the switch remains off for a minimum of 260ns.If FB is below the reference at that time the switch turns on again for another on-time period.The switching will continue until regulation is achieved.The regulator will operate in discontinuous conduction mode at light load currents,and continuous conduction mode with heavy load current.In discontinuous conduction mode (DCM),current through the output inductor starts at zero and ramps up to a peak during the on-time,then ramps back to zero before the end of the off-time.The next on-time period starts when the voltage at FB falls below the internal refer-ence.Until then the inductor current remains zero and the load is supplied entirely by the output capacitor.In this mode the operating frequency is lower than in continuous conduc-tion mode,and varies with load current.Conversion effi-ciency is maintained since the switching losses are reduced with the reduction in load and switching frequency.The discontinuous operating frequency can be calculated ap-proximately as follows:(1)where R L =the load resistanceIn continuous conduction mode (CCM),current always flows through the inductor and never reaches zero during the off-time.In this mode,the operating frequency remains rela-tively constant with load and line variations.The CCM oper-ating frequency can be calculated approximately as follows:(2)The output voltage is set by two external resistors (R FB1,R FB2).The regulated output voltage is calculated as follows:V OUT =0.8V x (R FB1+R FB2)/R FB2(3)Start-up Regulator (V CC )The start-up regulator is integrated within LM3100.The input pin (VIN)can be connected directly to line voltage up to 36V,with transient capability to 40V.The V CC output regulates at 6V,and is current limited to 65mA.Upon power up,the regulator sources current into the external capacitor at V CC (C VCC ).C VCC must be at least 680nF for stability.When the voltage on the VCC pin reaches the under-voltage lockout threshold of 3.75V,the buck switch is enabled and the Soft-start pin is released to allow the soft-start capacitor (C SS )to charge.The minimum input voltage is determined by the dropout voltage of V CC ,and the V CC UVLO falling threshold ()3.7V).If VIN is less than )4.0V,the V CC UVLO activates to shut off the output.Regulation ComparatorThe feedback voltage at FB is compared to the internal reference voltage of 0.8V.In normal operation (the output voltage is regulated),an on-time period is initiated when the voltage at FB falls below 0.8V.The buck switch stays on for the on-time,causing the FB voltage to rise above 0.8V.After the on-time period,the buck switch stays off until the FB voltage falls below 0.8V.Bias current at the FB pin is nomi-nally 100nA.Over-Voltage ComparatorThe voltage at FB is compared to an internal 0.92V refer-ence.If the voltage at FB rises above 0.92V the on-time pulse is immediately terminated.This condition can occur if the input voltage,or the output load,changes suddenly.Once the OVP is activated,the buck switch remains off until the voltage at FB pin falls below 0.92V.The low side switch will stay on to discharge the inductor energy and until the inductor current decays to zero.The low side switch will be turned off.ON-Time Timer,ShutdownThe LM3100main switch is determined by the R ON resistor and the input voltage (V IN ),and is calculated from:(4)The inverse relationship with VIN results in a nearly constant frequency as V IN is varied.R ON should be selected for a minimum on-time (at maximum V IN )greater than 200ns for proper current limit operation.This requirement limits the maximum frequency for each application,depending on V IN and V OUT ,calculated from the following:L M 3100 10ON-Time Timer,Shutdown(Continued)(5)The LM3100can be remotely shut down by taking the EN pin below 1.1V.Refer to Figure 1.In this mode the SS pin is internally grounded,the on-timer is disabled,and bias cur-rents are reduced.Releasing the EN pin allows normal operation to resume.The voltage at the EN pin is between 1.5V and 3.0V,depending on V IN and the pull-up resistor.Current LimitCurrent limit detection occurs during the off-time by monitor-ing the re-circulating current through the low-side synchro-nous switch.Referring to Functional Block Diagram,when the buck switch is turned off,inductor current flows through the load,into PGND,and through the internal low-side syn-chronous switch.If that current exceeds 1.9A the current limit comparator toggles,forcing a delay to the start of the next on-time period.The next cycle starts when the re-circulating current falls back below 1.9A and the voltage at FB is below 0.8V.The inductor current is monitored during the low-side switch on-time.As long as the overload condi-tion persists and the inductor current exceeds 1.9A,the high-side switch will remain inhibited.The operating fre-quency is lower during an over-current due to longer than normal off-times.Figure 2illustrates the inductor current waveform.During normal operation the load current is low,the average of the ripple waveform.When an overload occurs the current ratch-ets up until it exceeds 1.9A.During the Current Limited portion of Figure 2,the current ramps down to 1.9A during each off-time,initiating the next on-time (assuming the volt-age at FB is <0.8V).During each on-time the current ramps up an amount equal to:(6)During this time the LM3100is in a constant current mode,with an average load current (I OCL )equal to 1.9A +∆I/2.20174704FIGURE 1.Shutdown Implementation20174705FIGURE 2.Inductor Current -Current Limit OperationLM310011N -Channel Buck Switch and DriverThe LM3100integrates an N-Channel buck (high-side)switch and associated floating high voltage gate driver.The gate drive circuit works in conjunction with an external boot-strap capacitor and an internal high voltage diode.A 33nF capacitor (C BST )connected between BST and SW pins pro-vides voltage to the high-side driver during the buck switch on-time.During each off-time,the SW pin falls to approxi-mately -1V and C BST charges from the V CC supply through the internal diode.The minimum off-time of 260ns ensures adequate time each cycle to recharge the bootstrap capaci-tor.SoftstartThe soft-start feature allows the converter to gradually reach a steady state operating point,thereby reducing start-up stresses and current surges.Upon turn-on,after V CC reaches the under-voltage threshold,an internal 8µA current source charges up the external capacitor at the SS pin.The ramping voltage at SS (and the non-inverting input of the regulation comparator)ramps up the output voltage in a controlled manner.An internal switch grounds the SS pin if V CC is below the under-voltage lockout threshold,if a thermal shutdown oc-curs,or if the EN pin is ing an externally controlled switch,the output voltage can be shut off by taking the SS pin to ground.Releasing the switch allows the SS pin to ramp up,and the output voltage to return to normal.The shut-down configuration is shown in Figure 3.Thermal ProtectionThe LM3100should be operated so the junction temperature does not exceed the maximum limit.An internal Thermal Shutdown circuit,which activates (typically)at 165˚C,takes the controller to a low power reset state by disabling the buck switch and the on-timer,and grounding the Softstart pin.This feature helps prevent catastrophic failures from accidental device overheating.When the junction temperature falls back below 145˚C (typical hysteresis =20˚C),the Softstart pin is released and normal operation resumes.Applications InformationEXTERNAL COMPONENTSThe following guidelines can be used to select the external components.R FB1and R FB2:The ratio of these resistors is calculated from:R FB1/R FB2=(V OUT /0.8V)-1R FB1and R FB2should be chosen from standard value resis-tors in the range of 1.0k Ω-10k Ωwhich satisfy the above ratio.For V OUT =0.8V,the FB pin can be connected to the output directly.However,the converter operation needs a minimum inductor current ripple to maintain good regulation when no load is connected.This minimum load is about 10µA and can be implemented by adding a pre-load resistor to the output.R ON :The minimum value for RON is calculated from:Equation 1can be used to select R ON if a specific frequency is desired as long as the above limitation is met.L:The main parameter effected by the inductor is the output current ripple amplitude (I OR ).The maximum allowable (I OR must be determined at both the minimum and maximum nominal load currents.At minimum load current,the lower peak must not reach 0mA.At maximum load current,the upper peak must not exceed the current limit threshold (1.9A).The allowable ripple current is calculated from the following equations:I OR(MAX1)=2x I O(min)orI OR(MAX2)=2x (1.9A -I O(max))The lesser of the two ripple amplitudes calculated above is then used in the following equation:(7)where V IN is the maximum input voltage and Fs is deter-mined from equation 1.This provides a value for L.The next larger standard value should be used.L should be rated for the I PK current level shown in Figure 2.Inductor Selector for V OUT =3.3V2017473620174706FIGURE 3.Alternate Shutdown ImplementationL M 3100 12Applications Information(Continued)Inductor Selector for V OUT=0.8V20174737C VCC:The capacitor on the V CC output provides not onlynoise filtering and stability,but also prevents false triggeringof the V CC UVLO at the buck switch on/off transitions.Forthis reason,C VCC should be no smaller than680nF forstability,and should be a good quality,low ESR,ceramiccapacitor.C O and C O3:C O should generally be no smaller than10µF.Experimentation is usually necessary to determine the mini-mum value for C O,as the nature of the load may require alarger value.A load which creates significant transients re-quires a larger value for C O than a fixed load.C O3is a small value ceramic capacitor to further suppresshigh frequency noise at V OUT.A47nF is recommended,located close to the LM3100.C IN and C IN3:C IN’s purpose is to supply most of the switchcurrent during the on-time,and limit the voltage ripple at V IN,on the assumption that the voltage source feeding V IN hasan output impedance greater than zero.If the source’s dy-namic impedance is high(effectively a current source),itsupplies the average input current,but not the ripple current.At maximum load current,when the buck switch turns on,thecurrent into V IN suddenly increases to the lower peak of theinductor’s ripple current,ramps up to the peak value,thendrop to zero at turn-off.The average current during theon-time is the load current.For a worst case calculation,C INmust supply this average load current during the maximumon-time.C IN is calculated from:(8)where I O is the load current,t ON is the maximum on-time,and∆V is the allowable ripple voltage at V IN.C IN3’s purpose is to help avoid transients and ringing due tolong lead inductance at V IN.A low ESR,0.1µF ceramic chipcapacitor is recommended,located close to the LM3100.C BST:The recommended value for CBST is33nF.A highquality ceramic capacitor with low ESR is recommended asC BST supplies a surge current to charge the buck switch gateat turn-on.A low ESR also helps ensure a complete rechargeduring each off-time.C SS:The capacitor at the SS pin determines the soft-starttime,i.e.the time for the reference voltage at the regulationcomparator,and the output voltage,to reach their final value.The time is determined from the following:C FB:If output voltage is higher than1.6V,this feedback capis needed for Discontinuous Conduction Mode to improvethe output ripple performance,the recommended value forC FB is10nF.PC BOARD LAYOUTThe LM3100regulation,over-voltage,and current limit com-parators are very fast,and will respond to short durationnoise yout considerations are therefore critical foroptimum performance.The layout must be as neat andcompact as possible,and all of the components must be asclose as possible to their associated pins.Refer to thefunctional block diagram,the loop formed by C IN,the highand low-side switches internal to the IC,and the PGND pinshould be as small as possible.The PGND connection to Cinshould be as short and direct as possible.There should beseveral vias connecting the Cin ground terminal to theground plane placed as close to the capacitor as possible.The boost capacitor should be connected as close to the SWand BST pins as possible.The feedback divider resistorsand the C FB capacitor should be located close to the FB pin.A long trace run from the top of the divider to the output isgenerally acceptable since this is a low impedance node.Ground the bottom of the divider directly to the GND(pin7).The output capacitor,C OUT,should be connected close tothe load and tied directly into the ground plane.The inductorshould connect close to the SW pin with as short a trace aspossible to help reduce the potential for EMI(electro-magnetic interference)generation.If it is expected that the internal dissipation of the LM3100will produce excessive junction temperatures during normaloperation,good use of the PC board’s ground plane can helpconsiderably to dissipate heat.The exposed pad on thebottom of the IC package can be soldered to a ground planeand that plane should extend out from beneath the IC to helpdissipate the heat.The exposed pad is internally connectedto the IC substrate.Additionally the use of wide PC boardtraces,where possible,can help conduct heat away from theing numerous vias to connect the die attach pad to aninternal ground plane is a good practice.Judicious position-ing of the PC board within the end product,along with theuse of any available air flow(forced or natural convection)can help reduce the junction temperature.LM310013Applications Information(Continued)20174716Typical Application Schematic for V OUT =3.3V20174717Typical
