Description

PMP5236 uses parallel converters for Class 4 or high power PoE applications. The flyback converter with diode rectifier offers low cost solution while still achieving good efficiency. This reference design is well suited for PoE applications where power redundancy (12V@2A) or output power sharing (12V@4A) is needed. The TPS23754 contains both the PoE Powered Device and the PWM controller functions.
