This reference design generates three separate isolated 12V/0.77A outputs from either an 85-265VAC single phase input or a 200-480VAC-LL three phase input. The UCC28700 controls a flyback converter power stage. The primary side regulation feature of the UCC28700 eliminates the need for an optocoupler, reducing cost and complexity. The three outputs are isolated from each other and can be stacked in series to generate higher output voltages.
