Class 8 high power PoE isolated active clamp forward converter (24V/3A) reference design

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. In need of an IEEE802.3bt-ready PSE controller? Check out the TPS23881.
