PMP7355

Design files

Overview

This reference evaluation module, featuring the TPS23753A PoE interface and isolated converter controller, is used for class 3 PoE applications where low cost is required.

The flyback topology with diode rectifier results in a low cost converter with reasonable size and efficiency.

Features
  • Isolated non synchronous flyback
  • 5V at 2A output
  • Low cost
  • Uses TPS23753A IEEE 802.3-2005 PoE PD and PWM controller
  • Small board size
  • This circuit is fully functional tested and recommended for new designs
