The PMP11211 reference design uses the UCC28180 CCM PFC controller to generate a 380V/1kW output from a universal AC input. In addition to that, the UCC28722  PSR controller is used as bias supply in this design. Over 94% peak efficiency is achieved at  120VAC/60Hz input and over 97% efficiency is achieved at 230VAC/50Hz input with fixed 200kHz switching frequency.
