PMP9576
85V 至 265V AC 輸入、PSR 返馳架構的 12V/3.3A AC/DC 開放架構電源參考設計
PMP9576
概覽
This reference design provides an isolated 12V/3.3A output from a universal 85V-265V AC input. This design achieves efficiencies greater than 84%. Employing the UCC28710D Primary Side Regulation (PSR) Flyback controller eliminates the opto-coupler and secondary side regulation components. The energy saving features of the UCC28710D allow this design to consume less than 75mW when plugged into the wall with no device attached to the output.
特點
- Greater than 83% efficiency at full load (12V/3.3A)
- Less than 70mW of stand-by power consumption under no load
- Constant Current regulation feature of UCC28710D ensures output short-circuit protection
- Fast Start-up
