50.6W Valley Switching Flyback with Universal AC Input Reference Design


The PMP30251 reference design uses the UCC28740 flyback controller  to generate an isolated output 23V@2.2A from an universal AC input. The UCC28740 uses an optical coupler to regulate the output and to improve transient response. The valley-switching technique reduces switching losses and keeps the efficiency high.
