LM5158-Q1 flyback converter evaluation module

LM5158EVM-FLY

Overview

The LM5158EVM-FLY evaluation module showcases the features and performance of the LM5158 as a flyback converter to produce multiple output voltage rails for typical applications of the 3 phase inverter gate driver bias supplies.  The standard configuration is designed to provide a regulate output of 10 V at 250 mA from an input of 8 V to 16 V, and three isolated 20 V rails at 75 mA, 75 mA and 150 mA respectively.   The switching is at 250 kHz.

Features
  • Input voltage range: 8 V to 16V
  • Main output:  10 V, 250 mA
  • Isolated output 1: 20 V, 75 mA
  • Isolated output 2: 20 V, 75 mA
  • Isolated output 3: 20 V, 150 mA
  • Switching frequency:  250 kHz
