Overview

The LM5155EVM-SEPIC evaluation module showcases the features and performance of the LM5155 as wide input non-synchronous SEPIC controller. The standard configuration is designed to provide a regulated output of 12V at up to 2A from an input of 3V to 42V, switching at 2.2 MHz.

Features
  • Input voltage range: 3V to 42V
  • Output voltage 12V, up to to 2A
  • Switching frequency 2.2 MHz
  • Two layer PCB with single sided component population
