1 Introduction

The system under consideration is a typical buck SMPS circuit with D-CAP3™ control mode. There are many specific requirements in application. To realize a better performance, it is important to know the role of switching frequency in the power system. This application report analyzes the major power loss, output voltage ripple, and transient response and shows the solution size of different frequency at the end.
