The BP85924DA is a high performance, highlyintegrated power supply switcher iC with low standbyconsumption. The BP85924DA can be configured asbuck, buck-boost topologies for universal 85~265VACinputs. The BP85924DA integrates a 650 V power MOSFET, ahigh-voltage current source for self-biasing, a currentsensing circuit, an output feedback circuit and acontroller.ExternalVCccapacitorand loopcompensation components can be eliminated, whichreduces cost and size of overall power systems, andimproves reliability.
