1.1 Introduction

The LM5125AEVM-BST evaluation module provides a fully functional dual phase synchronous boost converter to evaluate LM5125A-Q1. The EVM operates over an input voltage range of 9V to 18V and supports input transients up to 42V. The EVM provides an output voltage of 24V with 240W rated power and 1kW peak power. Adjust the output voltage up to 45V via ATRK/DTRK pin.
