Description
- PMP12027, Valley Switching Flyback with 85 to 265VAC Input (48V @ 0.625A) Reference Design. The PMP12027 reference design uses the UCC28740 flyback controller to generate a 48V/625mA output from a universal AC input. The valley switching of the UCC28740 allows this design to achieve a maximum load efficiency over 90%, no load losses are less than 100mW. The constant current regulation mode of the UCC28740 provides accurate current limiting
