Class 3 isolated high-efficiency active clamp flyback converter for PoE power reference design

PMP40514

Design files

Overview

This reference design is developed for evaluating 13-W isolated active clamp flyback PD converter system using the IEEE 802.3at PoE interface and DC/DC controller TPS23756. The converter is capable of supporting the 13-W maximum IEEE 802.3at power requirements. It presents good efficiency, load regulation and related electrical performance.

Features
  • Support IEEE 802.3at-Compliant power devices
  • Combined PoE PD and DC/DC controller simplifies the design
  • High efficiency and better EMI performance with soft-switching technology
