Description

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

Features
  • Ethernet Alliance certified for receiving Class 3 power
  • High efficiency for both PoE supply power and adapter supply power (up to more than 90%)
  • The output is 5V/2.3A
  • Isolated Flyback with synchornous rectifier
  • Small size solution
  • Uses TPS23753APW with PoE interface PD and PWM controller
  • This circuit design is full-functional tested and recommended for new designs
