FEBFDMQ8203_90W, GreenBridge Evaluation Kit for Power Over Ethernet 90W Active Clamp Forward DC-DC Converter
Projekt referencyjny przez: onsemi
FEBFDMQ8203_90W, GreenBridge Evaluation Kit describes the proposed solution for PoE++ PD that increases the delivering power up to 90W. It is designed to rectify a polarity of DC voltage from Power Source Equipment (PSE) and then active clamp forward DC-DC converter steps down a nominal input voltage 48 VIN to output voltage 3.3 VOUT in 300 kHz of the switching frequency. To deliver 90 W power through a network cable, the power system is composed with four-pair architecture, which PSE uses to deliver data and power to the PD through both the spare pair and data pair in the network cable at the same time
