Overview

The LM5157EVM-FLY evaluation module showcases the features and performance of the LM5157 as a flyback converter to produce multiple output voltage rails for typical applications of the 3phase inverter gate driver bias supplies.  The standard configuration is designed to provide a regulated 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 16 V
  • 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
