85VAC-265VAC Input, 12V/3A Output Green-Mode Synchronous Flyback


Design files


The PMP4820 reference design use the UCC28600 green-mode controller with a synchronous rectifier to provide good efficiency at heavy loads while maintaining low power consumption at light loads. The maximum load efficiency is over 87%, and the no load losses are less than 150mW.
