Demonstration Circuit 2476A is an IEEE 802.3bt (Draft 2.2) compliant power over ethernet (PoE) powered device (PD). It features the LT®4295 PD interface and switching regulator controller and the LT4321 PoE ideal diode bridge controller.The LT4295 provides IEEE 802.3af (PoE, Type 1), IEEE802.3at (PoE+, Type 2), and IEEE 802.3bt (PoE++, Type 3and 4) compliant interfacing and power supply control. Itutilizes an external, low RDS(on) (30mΩ typical) N-channelFET for the hot swap function to improve efficiency. TheLT4295 controls a DC/DC converter that utilizes a highlyefficient flyback topology with synchronous rectification.
