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.
