TPS62903QRYTRQ1 TI Step-Down Converter | 9-VQFN-HR (2.2x2) | 3A, 2.5V-17V

Product Overview

The TPS62903QRYTRQ1 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 2.5V to 17V and delivers up to 3A of continuous output current. Housed in a compact 9-pin VQFN-HR package (2.2mm x 2mm), this device integrates low RDS(on) MOSFETs to achieve high efficiency and small solution size. The TPS62903QRYTRQ1 features a fixed 2.2MHz switching frequency, enabling the use of small inductors and capacitors, and supports 100% duty cycle for low dropout operation.
