This converter provides a high power PoE output of 5V/10A. 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.
• High efficiency (93% with PoE supply, 92% with adapter supply)
• 5V at 10A output
• Isolated Forward with synchronous rectifier
• Uses TPS2379 combined with UCC2897A to implement a high efficiency active forward converter
• Allows an external hot swap FET for increased efficiency
