TPS62903RPJR TI DC-DC Converter | 9-VQFN-HR (1.5X2) | 3A, 2.5V-17V

Product Overview

The TPS62903RPJR from Texas Instruments is a high-efficiency, low-noise, 3A step-down (buck) DC-DC converter with an integrated inductor. It operates over a wide input voltage range of 2.5V to 17V and provides a regulated output voltage as low as 0.6V. The device is housed in a compact 9-pin VQFN-HR package (1.5mm x 2mm), making it ideal for space-constrained applications. With its advanced architecture, the TPS62903 achieves up to 95% efficiency and features a low quiescent current of 17µA, extending battery life in portable devices.
