Description

TheLMG5200POLEVM-10EVMis designedto evaluatethe LMG5200GaNpowerstageandtheTPS53632Ghalf-bridgepoint-of-loadcontrollerin a 48-Vto 1-V application.This EVMimplementsthe 48-V to 1-V converteras a single-stagehard-switchedhalf-bridgewith current-doublerrectifier.Thistopologyefficientlysupportsa highstep-downratiowhileprovidingsignificantoutputcurrentand fast transientresponse.The TPS53632Gcontrollerusesa D-CAP+hystereticcontrolarchitectureto achievesuperiortransientresponse.The TPS53632Gis a variantof the TPS53632controller,modifiedto supportthe half-bridgetopologyusedin this EVM.The LMG5200is an 80-V,10-Ahalf-bridgepowerstageusinggallium-nitride(GaN)transistors.GaNofferssuperiorswitchingperformanceto traditionalsiliconMOSFETsdue to its lack of reverse-recoveryeffectandreducedinputandoutputcapacitance.By usinga GaNmodule,this applicationachieveshighefficiencywhileoperatingin a hard-switchedconfiguration.ThisEVMguidedescribescorrectoperationandmeasurementof the EVM,as wellas the EVMconstructionand typicalperformance
