13W 802.3af PoE Powered Device Interface with Flyback DC-DC Converter EV Board

Overview

TopologyFlyback Converter
Input voltage36-57 V
Output 112 V / 1 A
IC revision1.1

Description

The MP8004 is an integrated IEEE 802.3af PoE compliant Powered Device (PD) power supply solution. It includes a PD interface and an isolated/non-isolated flyback converter. The PD interface includes detection andclassification modes as well as a 100V output pass device. Inrush current limit is included to slowly charge the input capacitor.The DC-DC converter includes a 150V power switch and is capable of delivering 13W output power with high efficiency. It has an internalsoft-start, auto-retry, over current, short circuit, and over voltage protection. It can also skip cycles during light load condition.The MP8004 is available in thermally enhanced 4x6mm QFN20 package.
