TPS62224DDCT TI Step-Down Converter | SOT-23-THIN | 2.25MHz, 400mA

Product Overview

The TPS62224DDCT from Texas Instruments is a high-efficiency, synchronous step-down DC-DC converter optimized for battery-powered and portable applications. Housed in a compact SOT-23-THIN package, it delivers up to 400 mA output current with a 2.25 MHz fixed switching frequency, enabling small external components. The device operates from a 2.5V to 6V input voltage range, making it suitable for single-cell Li-Ion, multi-cell alkaline, or NiMH batteries. Its high efficiency (up to 95%) extends battery life in power-sensitive designs.
