PMP10344
85V 至 480V AC 輸入、三路輸出 (12V/0.7A) AC/DC 返馳參考設計
PMP10344
概覽
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.
特點
- Accepts 3 phase input voltages up to 480VAC, as well as single phase 85-264VAC
- Generates three separate isolated 12V/0.7A outputs that can be stacked in series or in parallel for different output voltages/currents
- Delivers 25W total output power
- Start-up time <200ms (at 230VAC or higher), <400ms (115VAC
- Features 960V N-channel power MOSFET switch
- Primary Side Regulation eliminates optocoupler, reduces cost, increases reliability
