Abstract

Soft start is a common feature used in DC/DC buck converters. Soft start can prevent excessive inrush current and maintain a controlled output voltage during power on. This application note aims to provide a better understanding of TPS56837 soft start. First, this document introduces soft start and covers the general principle of soft start, both internal and external soft start are illustrated. Then, this documents analyzes behaviors related to soft start. Finally, guidance of how to co-lay TPS56837 and TPS56637 is provided.
