PMP6812
適用於 PoE 應用的第 4 級成本最佳化返馳式轉換器參考設計
PMP6812
概覽
This reference evaluation module, featuring the TPS23754 PoE interface and DC-to-DC controller is used for class 4 PoE applications.
The flyback topology with diode rectification results in a low-cost converter for PoE applications such as a security camera. With the appropriate BOM changes, PMP6812 can also operate as a 13W supply.
特點
- Isolated non-synchronous flyback
- 12V at 1.8A output
- Good efficiency (84%) at low cost
- Uses TPS23754 high-power, high-efficiency PoE interface PD and PWM controller
- The circuit design is full-functional tested and recommended for new designs.
