TPS62229DDCT TI Step-Down Converter | SOT-23-THIN | 2.25MHz, 400mA

Product Overview

The TPS62229DDCT 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 6.5V input voltage range, making it suitable for single-cell Li-Ion or 3-cell alkaline/NiCd/NiMH batteries. Advanced features include power-save mode for light-load efficiency, 100% duty cycle for low dropout, and output voltage accuracy of ±1.5%.
