TPS61253YFFT TI DC-DC Converter | 9-DSBGA | 3.5A Switch, 2.3-5.5V Input

Product Overview

The TPS61253YFFT from Texas Instruments is a high-efficiency, low-quiescent-current boost converter with a 3.5A integrated switch. It operates from an input voltage range of 2.3V to 5.5V and can deliver an output voltage up to 5.5V. The device is housed in a compact 9-pin DSBGA package (YFF), making it ideal for space-constrained applications. With a typical quiescent current of 17µA and a shutdown current of 1µA, it is optimized for battery-powered systems requiring extended battery life.
