Product Introduction

Overview

The TPS564242DRLR, produced by Texas Instruments, is a high-efficiency, synchronous buck converter designed for a wide range of applications. This device operates with an input voltage range of 3 V to 16 V and can deliver an output voltage from 0.6 V to 7 V, supporting up to 4 A of continuous current. It features the proprietary D-CAP3 control topology, which provides fast transient response without the need for external compensation components. The TPS564242DRLR is available in a compact 6-pin SOT-563 package, making it ideal for applications requiring high power density and small solution size.
