IEEE 802.3bt PD Interface with Forward/Flyback Controller

Overview

TopologyFlyback Converter
Switching frequency214-300 kHz
Output 112 V / 4 A

Description

The LT®4295 is an IEEE 802.3af/at/bt(Draft 2.0)-compliantpowered device (PD) interface controller with aswitching regulator controller. The T2P output indicatesthe number of classification events received during IEEE802.3bt-compliant mutual identification and negotiationof available power.
