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

Overview

TopologyLAN / POE
Input voltage37-57 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. ICs used: TPS2373 - https://www.we-online.com/en/components/icref/texas-instruments/TPS2373-PMP21318-LAN-POE UCC2897A - https://www.we-online.com/en/components/icref/texas-instruments/UCC2897A-PMP21318-Forward

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
