High Efficiency Isolated Flyback Converter EV Board

Overview

TopologyFlyback Converter
Input voltage36-72 V
Output 15 V / 5 A
IC revision1.0

Description

The EV3908DK-01A is an evaluation board for the MP3908DK. It is configured to provide a regulated 5V output at up to 5A load current from a 36V-72V input. The output is adjustable by changing feedback resistors on the evaluation board. MP3908DK features a synchronous gate output which enables high efficiency design by relating the schottky rectifier by a MOSFET.

Features

  • Isolated High Efficiency 25W Design
  • Current Mode Control
  • Under-Voltage Lockout
  • Cycle-by-Cycle Current Limiting
  • 10μA Shutdown Current
  • 180μA Quiescent Current
  • 250KHz Constant Frequency Operation

Typical applications

  • Power over Ethernet (PoE), TV CCFL Power Generation, Telecom Isolated Power
