TPS62737RGYT TI Step-Down Converter | 14-VQFN (3.5x3.5) | 300mA, 2.2V-5.5V

Product Overview

The TPS62737RGYT from Texas Instruments is a high-efficiency step-down (buck) DC-DC converter designed for ultra-low power applications. It operates from an input voltage range of 2.2V to 5.5V and delivers up to 300mA output current. The device features a proprietary power-save mode that reduces quiescent current to 15µA, making it ideal for battery-powered and energy-harvesting systems. Housed in a compact 14-pin VQFN package (3.5mm x 3.5mm), it offers a small footprint for space-constrained designs.
