1 Introduction

A common control topology employed in buck regulators is constant-on-time (COT). This control topology is being adopted in several 48-V battery and eBike, pre-regulators such as LM5013-Q1. This application note is an overview of how line and load regulation can be optimized with LM5013-Q1 for wide-VIN range applications, specifically, the 48 V battery and eBike applications.
