1.1 Introduction

The LM5126AEVM-BST evaluation module provides a fully functional single phase synchronous boost converter to evaluate LM5126A-Q1. The EVM operates over an input voltage range of 9V to 18V and can handle input transients up to 42V. The EVM provides an output voltage of 24V with 150W rated power and 500W peak power. The output voltage is adjustable up to 45V via ATRK/DTRK pin. The LM5126AEVM-BST evaluation module can be stacked with a LM5125AEVM-BST evaluation module for 3-phase operation.
