Analog Devices LT4295

IEEE 802.3bt PD Interface with Forward/Flyback Controller

Overview

TopologyForward Converter
Input voltage37-57 V
Switching frequency214-300 kHz
Output 15 V / 13 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.

Features

IEEE 802.3af/at/bt(Draft 2.0) Powered Device (PD)with Forward/Flyback Controllern Supports Up to 71 Watt PDsn 5-Event Classification Sensingn Superior Surge Protection (100V Absolute Maximum)n Wide Junction Temperature Range (–40°C to 125°C)n >94% End-to-End Efficiency with LT4321 Ideal Bridgen External Hot Swap N-Channel MOSFET for LowestPower Dissipation and Highest System Efficiencyn No-Opto Flyback Operationn Auxiliary Power Support as Low as 9Vn Easy Migration of LTPoE++® PDs to IEEE 802.3bt PDsn Pin Compatible with LT4276A/B/Cn 28-Lead 4mm × 5mm QFN Package
