PMP4408
離線 AC/DC 120W 多輸出返馳電源供應參考設計
PMP4408
概覽
The PMP4408 is a universal AC input, 120W flyback converter reference design. The LM5023 Quasi Resonant Flyback converter was chosen to get 2 high-efficiency isolated outputs. Additionally a downstream Buck converter, the TPS5402 enables 2 high-efficiency non-isolated outputs. The QR Flyback design implements Valley switching for high-efficiency and full protection features such as output short circuit and output overvoltage.
特點
- Good cross regulation
- Valley switching for high efficiency
- Output OVP, OCP and Short Circuit Protection
- Input brown-out
- Average efficiency is high
- Size 92mm(L) x 95mm(W) x 30mm(H)
