This reference design generates a non-isolated 15V/25mA output from a 100V-400V DC input. It is intended to be used as an auxillary bias supply in off-line applications. It can be connected directly to the bulk input cap, after the bridge rectifier in most AC/DC system. The UCC28910 with integrated 700V MOSFET controls a simple flyback converter power stage. The variable switching frequency control method and valley switching of the UCC28910 reduce losses. This highly integrated design consumes very little board space and is comprised of only 13 components.
