Referenzdesign von: Texas Instruments
PMP9727.2, 120VAC Input, 48V/12V 32W Flyback Reference Design. The PMP9727 reference design uses the UCC28740 flyback controller to generate both a 12V/1A and 48V/0.4A outputs from a 120V AC input. The valley switching of the UCC28740 allows this low-cost design to provide an efficiency of over 89%, no load losses are less than 80mW
