Peak Current Mode PWM Controller Flyback Evaluation Board

Overview

TopologyFlyback Converter
Input voltage36-72 V
Output 112 V / 2.5 A
IC revision1.1

Description

The EV3910-K-00A evaluation board is designed to demonstrate the capabilities of the MP3910. The MP3910 is a peak current control mode PWM controller that can drives an external MOSFET capable of handling >10A current. It can accommodate flyback and boost for isolated and non-isolated applications.
