When it comes to Class 3 PoE applications where high efficiency and isolation are required, you can use TI's PMP9175 converter.
The output for this device is 5V/2.3A. Superb efficiency and small size for POE applications such as a IP Phones are achievable thanks to itsisolated flyback converter with synchronous rectifier.
Worth noting: TI's TPS23753APW contains both the POE-Powered Device and the PWM controller functions.
For both POE supply power and adapter supply power, the PMP9175 is highly efficient (more than 90%). The circuit design is full-functional tested and recommended for new designs.
