85-480VAC Input: Triple Ouput (12V/0.7A) AC/DC Flyback Reference Design
Description
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.
Features
- Accepts 3 phase input voltages up to 480VAC: as well as single phase 85-264VACGenerates three separate isolated 12V/0.7A outputs that can be stacked in series or in parallel for different output voltages/currentsDelivers 25W total output powerStart-up time Features 960V N-channel power MOSFET switchPrimary Side Regulation eliminates optocoupler: reduces cost: increases reliability
