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

Overview

TopologyFlyback Converter
Input voltage36-57 V
Switching frequency227-278 kHz
Output 112 V / 1 A
IC revision001

Description

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

Typical applications

  • IEEE 802.3at Compliant Devices / Video and VoIP Telephones / Security Cameras
  • RFID Readers / Multiband Access Points
