1.1 Introduction

The LM5125EVM-BST evaluation module provides a fully functional dual phase synchronous boost converter to evaluate LM5125-Q1. The EVM operates over an input voltage range of 8V to 18V and can handle input transients up to 42V. The EVM provides an output voltage of 24V with 300W rated power and 1kW peak power. The output voltage can also be adjusted up to 45V via ATRK/DTRK pin. Two EVMs can be stacked to support 4-phase operation.
