TPS561208DDCR TI Synchronous Buck Converter | SOT-23-THIN | 1A, 4.5V-17V

Product Overview

The TPS561208DDCR from Texas Instruments is a high-efficiency, synchronous step-down (buck) DC-DC converter capable of delivering up to 1A of continuous output current. It operates over a wide input voltage range of 4.5V to 17V, making it suitable for a variety of applications including industrial, automotive, and consumer electronics. The device integrates both high-side and low-side MOSFETs, minimizing external component count and simplifying design. With a fixed switching frequency of 580kHz, it offers a good balance between efficiency and solution size. The TPS561208DDCR is available in a compact SOT-23-THIN package, ideal for space-constrained designs.
