TPS6281220QWRWYRQ1 TI Step-Down Converter | 9-VQFN-HR (3x2) | 2.7V-6V Input, 1A Output

Product Overview

The TPS6281220QWRWYRQ1 from Texas Instruments is a high-efficiency, synchronous step-down (buck) converter designed for automotive and industrial applications. It operates over a wide input voltage range of 2.7V to 6V and delivers up to 1A of continuous output current. The device is housed in a compact 9-pin VQFN-HR package measuring 3mm x 2mm, making it ideal for space-constrained designs. With integrated MOSFETs, low quiescent current, and a switching frequency of 2.2 MHz, it provides excellent transient response and high efficiency across the load range.
