18.5V to 57V Aux-Input to 5.3V: 10W PoE Isolated Sync-Flyback Reference Design

Description

This compact reference design is a typical PoE application: supplying 10W at 5.3V from Ethernet power. Data filter: external auxiliary input and EMI filter are all on board. The synchronous rectification improves the efficiency: important at only 5.3V output voltage.

Features
  • Good efficiency for this class of power: 91% @ 48Vin (PoE input): full loadCompact solution: without connectors and data filter: only 40mm x 60mmThe board can be configured to work with and without synchronous rectification
