TIDA-00618
具有 PSR 的 8.5W 雙路輸出 (5V/12V) 通用輸入 AC/DC 隔離式返馳參考設計
TIDA-00618
概覽
The TIDA-00618 reference design is a Primary Side Regulation switcher which provides isolated dual outputs, 5V and 12V rails, with DC stacking of the secondaries to provide output voltage regulation that is equivalent to opto-coupler based solution.
Low system parts count and built in advanced protection features result in a cost-effective solution with an average efficiency of nearly 75% at 230V
特點
- Isolated 5V and 12V output at 500mA maximum
- Conducted EMI compliant
- 100ms typical start-up time
- Primary side control eliminates need for optocoupler
- Input under & Output over voltage protection
- Primary over current protection
- Controlled start up and restart after fault Protection
