HystereticControlCircuitOverview The LM25007 is a Buck DC-DC regulatorthatuses a constanton-timecontrolscheme. The on-timeis programmed by an externalresistorand variesinverselywithlineinputvoltage(Vin).The core regulation elementsoftheLM25007 arethefeedbackcomparatorand theon-timeone-shot.The regulatoroutputvoltageis sensed at the feedbackpin(FB) and iscompared to an internalreferencevoltage(2.5V).Ifthe FB signalis below thereferencevoltage,thebuck switchisturnedon fora fixedtimepulsedeterminedby thelinevoltage and a programmingresistor(RON ).Followingtheon periodtheswitchwillremainoffforatleasttheminimum off timerperiodof300ns.IftheFB pinvoltageisstillbelowthereferenceafterthe300ns off-time,theswitchwillturn on againforanotheron timeperiod.ThisswitchingbehaviorwillcontinueuntiltheFB pinvoltagereachesthe referencevoltagelevel. The LM25007 operatesindiscontinuousconductionmode atlightloadcurrentsorcontinuousconductionmode atheavierloadcurrents.Indiscontinuousconductionmode, currentthroughtheoutputinductorstartsatzeroand ramps up toa peak valueduringthebuck switchon-timeand thenback tozeroduringtheoff-time.The inductor currentremains at zero untilthe next on-timeperiodstartswhen FB fallsbelow the internalreference.In discontinuousmode theoperatingfrequencyisrelativelylow and willvarywithload.Thereforeatlightloadsthe conversionefficiencyismaintained,sincetheswitchinglossesdecreasewiththereductioninloadcurrentand switchingfrequency.The approximatediscontinuousmode operatingfrequencycan be calculatedas follows: (1) Incontinuousconductionmode, currentflowscontinuouslythroughtheinductorand neverramps down tozero. Inthismode theoperatingfrequencyisgreaterthanthediscontinuousmode frequencyand remainsrelatively constantwithloadand linevariations.The approximatecontinuousmode operatingfrequencycan be calculated as follows: (2) The outputvoltage(Vout)can be programmed by two externalresistorsas shown inFigure6. The regulated voltageiscalculatedas follows: VOUT = 2.5x (R3 + R4) /R4 (3) The feedbackcomparatorin hystereticregulatorsdepends on the outputripplevoltageto switchthe output transistoron and offatregularintervals.Inorderfortheinternalcomparatortorespondquicklytochanges in outputvoltage,proportionalto inductorcurrent,a minimum amount of capacitorEquivalentSeriesResistance (ESR) isrequired.A ripplevoltageof25mV isrecommended atthefeedbackpin(FB)forstableoperation.In caseswhere theintrinsiccapacitorESR istoosmall,additionalseriesresistancemay be added.

N -Channel Buck Switch and Driver The LM25007 integratesan N-Channel Buck switchand associatedfloatinghighvoltagegatedriver.The gate drivercircuitworks inconjunctionwithan externalbootstrapcapacitorand an internalhighvoltagediode.The bootstrapcapacitorischarged by VCC throughthe internalhigh voltagediode.A 0.01uF ceramiccapacitor connectedbetween theBST pinand SW pinisrecommended. Duringeach cyclewhen theBuck switchturnsoff,theSW pinisapproximately0V. When theSW pinvoltageis low,thebootstrapcapacitorischargedfromVcc throughtheinternaldiode.The minimum offtimer,setto300ns, ensuresthattherewillbe a minimum intervaleverycycletorechargethebootstrapcapacitor.
