Non-Standard (>25.5W) PoE - High Efficiency Forward Converter (12V@5A) Reference Design
Description
This converter provides a high power PoE output of 12V/5A. The TPS2379 PD controller allows the use of an external hot swap FET for increased efficiency. The UCC2897A PWM controller is used to implement a high efficiency active clamp forward converter.
Features
- High efficiency (90% with PoE supply: 93.6% with adapter supply) 12V at 5A output Isolated Forward with synchornous rectifier Uses TPS2379 combined with UCC2897A to implement a high efficiency active forward converter Allows an external hot swap FET for increased efficiency This circuit design is full-functional tested and recommended for new designs
Applications
