Texas Instruments TPS2373-3 | Demoboard TIDA-050023

Type-3 IEEE802.3bt-ready flyback converter PoE powered device reference design

Overview

TopologyFlyback Converter
Input voltage42-57 V
Output 112 V / 4.25 A
IC revisionA

Description

This design showcases a low cost, Type-3, Class 6, 51W flyback converter for powered devices through Power over Ethernet. The TPS2373-3 PD controller provides detection and classification while also powering up the LM51551-Q1 PWM controller through its advanced startup feature. This design takes in a 42V-57V PoE input and outputs a 12V rail for applications such as IP network cameras and wireless access points.

Features

  • Supports power levels for IEEE802.3bt Type 3
  • Isolated diode rectified flyback design
  • Built in hiccup mode protection for superior thermal performance during faults
  • PD Advanced Startup for PWM controller
  • Automatic Maintain Power Signature (MPS)
  • Oring circuit for auxiliary power through AC/DC

Typical applications

  • IP Network Cameras, Wireless Access Points
  • Other >25-W PoE PD Design
