Class 8 High Power PoE Isolated Active Clamp Forward Converter (24V/3A) Reference Design

Overview

TopologyForward Converter
Input voltage40-57 V
Output 124 V / 3 A
IC revisionA

Description

This reference design is a high power PoE Powered Device (PD) plus active clamp forward converter. The TPS2373 high power PD controller EVM (TPS2373-4EVM-758) provides all functions necessary to implement an IEEE802.3bt-ready PD. This is paired up with an active clamp forward converter utilizing the UCC2897A controller. The high efficiency 24V/3A output using synchronous rectifiers is ideally suited for high power PoE applications such as IP security cameras and LED lighting applications.
