TPS628691ARQYR TI DC-DC Converter | 9-VQFN-HR (1.5x2.5) | 2.7V-6V Input, 1A Output

Product Overview

The TPS628691ARQYR from Texas Instruments is a high-efficiency, low-ripple step-down DC-DC converter designed for space-constrained applications. Housed in a compact 9-pin VQFN-HR package (1.5mm x 2.5mm), it delivers up to 1A continuous output current from an input voltage range of 2.7V to 6V. With a typical quiescent current of 4µA, it is ideal for battery-powered devices requiring extended runtime. The device integrates a 0.6V reference voltage and supports output voltages as low as 0.6V, making it suitable for powering modern low-voltage digital cores.
