A 600-W Interleaved Dual-Phase Transition Mode PFC Converter (Rev. A)

PR735 is an interleaved dual-phase transition-mode PFC converter providing a fixed 400-V output at up to 1.5 A from an 85 VRMS to 265 VRMS ac input supply. This reference design requires an additional bias voltage of 15 V at 100 mA to power the UCC28060 device. PR735 is designed to showcase the features of the UCC28060 by demonstrating the performance of the UCC28060 in a typical off-line high power application.
