PMP8787
具有 85V 至 265V AC 輸入 (12V @ 0.5A) 的初級側穩壓返馳參考設計
PMP8787
概覽
The PMP8787 reference design uses the UCC28700 flyback controller to generate a 12V/500mA output from a universal AC input. The primary-side regulation technique implemented by the UCC28700 eliminates the need for an opto coupler, reducing the size and cost of the design. In addition, the valley switching of the UCC28700 allows this design to achieve a maximum load efficiency over 80%; no load losses are less than 40mW. The circuit board measures only 28mm by 33mm, with a maximum height below 20mm.
特點
- Primary Side Regulation (no optocoupler)
- Standby (no load) power consumption is less than 40mW
- Conducted emissions are below Class B levels
- Compact form factor 28mm X 33mm X 20mm
