1.1 Introduction

The TPS562242B 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 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 and enters Eco-mode in light load conditions. The high-side and low-side switching MOSFETs are incorporated inside the TPS562242B package along with the gate-drive circuitry. The TPS562242B DC/DC synchronous converter is designed to support up to a 2A continuous current from an input voltage source of 3V to 17V. The output voltage range is from 0.6V to 10V. Table 1-1 gives rated input voltage and output current ranges for the evaluation module.
