PMP10236 Reference Design

Texas Instruments

Dual-Output 5V at 300mA and 15V at 100mA Isolated Flyback From 85V to 440V AC Mains Reference Design


This is an isolated quasi-resonant flyback converter: supplying 5 V at 300 mA and 15 V at 100 mA; both outputs are isolated from each other. The UCC28722 has been chosen to drive a low-cost high-voltage BJT transistor.
