Product Introduction

Overview

The TPS562209DDCT from Texas Instruments is a 2-A synchronous step-down voltage regulator integrated into a compact 6-pin SOT-23 package. This device is designed to operate with a minimal number of external components, making it an efficient and space-saving solution for various power supply needs. It features an input voltage range of 4.5 V to 17 V and an output voltage range of 0.76 V to 7 V, making it versatile for different applications. The regulator employs D-CAP2™ mode control, which provides fast transient response and supports both low ESR and ceramic output capacitors without external compensation components.
