TPS2121RUXT TI Power Management IC | 12-VQFN-HR (2x2.5) | 2.7V-22V, 4.5A

Product Overview

The TPS2121RUXT from Texas Instruments is a high-performance power multiplexer (Power MUX) designed for seamless power source selection and OR-ing in systems with multiple input power sources. It supports an input voltage range of 2.7V to 22V and can handle continuous currents up to 4.5A. Housed in a compact 12-pin VQFN-HR package (2mm x 2.5mm), this device is ideal for space-constrained applications requiring efficient power path management.
