PMP10143.1, Universal AC Input, Dual Output (12V @ 30mA) Isolated Flyback Converter Reference Design

PMP10143.1, Universal AC Input, Dual Output (12V @ 30mA) Isolated Flyback Converter Reference Design. The PMP10143 reference design demonstrates the use of UCC28880 high-voltage switcher to design an Offline Isolated Flyback converter that can supply greater than 100mA output current. Using 2ndary side feedback control, the design delivers a tightly regulated 3.3V/400mA output that can be used to bias microcontrollers and DSPs. In addition the design also provides a 2nd output rail of 12V/30mA that can be used to supply relays and other analog devices
