PMP9561
針對空載零功耗最佳化的 5V/10W 離線 DCM 返馳式轉換器 - 參考設計
PMP9561
概覽
This design features the UCC28730 flyback controller in conjunction with the UCC24650 wake-up monitor to provide CV, CC regulated output with ultra-low stand-by power that exceeds Level VI and CoC Tier 2 specifications for average efficiency and 10% load efficiency. Wake-up signal detection provides fast transient response to large load steps.
特點
- No-Load Stand-By Power Consumption less than 5 mW
- Wake-Up Detection for Fast Dynamic Response
- Primary Side Regulation Eliminates Opto-Coupler
- Average Efficiency > 83%; exceeds Level VI and CoC Tier 2 specifications, effective 2016
- 10% efficiency > 80%
- Resonant Ring Valley Switching Operation for Highest Overall Efficiency
