Class 4: Efficiency-Optimized: Flyback Converter Reference Design for PoE Applications


This reference evaluation module: featuring the TPS23754 PoE interface and DC-to-DC controller: is used for Class 4 PoE applications where high efficiency is required. Output power is 5V at 5A from either an adapter input(21.6-57VDC) or power over ethernet. in general: the efficiency gain is on the order of 3-4%.
