Universal AC Input: Dual Output (12V@30mA: 3.3V@400mA) Isolated Flyback Converter Reference Design
Description
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 tighly regulated 3.3V/400mA output that can be used to bias micontrollers 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.
