Class 8 PoE 12-V, 6-A, powered device (PD) active-clamp forward converter reference design

Overview

TopologyForward Converter
Input voltage18-110 V
Output 112 V / 6 A
IC revisionC

Description

This reference design features a Type-4, Class 8, 71-W active clamp forward converter for powered devices (PD) through Power over Ethernet (PoE). The TPS2373-4 PD controller provides detection and classification and also powers up the UCC2897A pulse-width modulation (PWM) controller through its advanced start-up feature.

Features

  • Supports power levels for IEEE802.3bt Type-4
  • Automatic maintain power signature (MPS)
  • Advanced start-up
  • Synchronous rectifiers for high efficiency

Typical applications

  • High-efficiency DC-to-DC power supplies
  • Server power, 48-V telecom, datacom, and 42-V automotive applications
