PMP9175
適用於 PoE 應用的 3 級 5V/2.3A 高效率同步返馳式轉換器參考設計
PMP9175
概覽
This converter is used for Class 3 PoE applications where high efficiency and isolation are required. The specific output for this design is 5V@2.3A. The flyback converter with synchronous rectifier provides excellent efficiency and small size for PoE applications such as a IP Phones. The TPS23753APW contains both the PoE Powered Device and the PWM controller functions
特點
