1 Introduction

The LM5123EVM-BST evaluation module is designed to evaluate the operation and performance of the LM5123-Q1 low-IQ synchronous boost controller. The EVM operates over an input voltage range of 8-V to 18-V and can handle input transients up to 42-V. The EVM provides a 24-V output with a maximum power rating of 200-W. The output voltage can be to 33-V while using the TRK pin of the LM5123-Q1. The EVM can be used to evaluate the LM5123-Q1 for many applications. Figure 1-1 shows the standard application circuit for the LM5123EVM-BST evaluation module.
