1.1 Introduction

The TPS56224x is a single, adaptive on-time, D-CAP3™ control mode, synchronous buck converter that requires a very low external component count. The D-CAP3 control mode circuit is optimized for low-ESR output capacitors such as POSCAP, SP-CAP, or ceramic types and features fast transient response with no external compensation. The switching frequency is internally set at a nominal 1.2MHz. The TPS56224x DC/DC synchronous converter is designed to support up to a 2A continuous current from an input voltage source of 4.2V to 17V.

This user's guide mainly introduces the TPS56224x features as well as support documentation for the TPS56224xEVM. This document includes the performance specifications, board layout, schematic and bill of materials.
