TPS562219ADDFT TI Step-Down Regulator | TSOT-23-8 | 4.5V-17V Input, 2A Output

Product Overview

The TPS562219ADDFT from Texas Instruments is a high-efficiency, synchronous step-down (buck) DC-DC converter designed for space-constrained applications. It integrates both high-side and low-side MOSFETs, enabling a compact solution with minimal external components. The device operates over a wide input voltage range of 4.5V to 17V and delivers up to 2A of continuous output current. With a fixed switching frequency of 580kHz, it offers a good balance between efficiency and component size. The TPS562219ADDFT is available in a small TSOT-23-8 package, making it ideal for portable and industrial applications.
