TPS2121RUXR TI Power Management IC | 12-VQFN-HR(2x2.5) | 2.7V-5.5V, 1.5A

Product Overview

The TPS2121RUXR from Texas Instruments is a high-performance power multiplexer (Power MUX) designed for seamless power source selection in systems with multiple input power sources. It supports an input voltage range of 2.7V to 5.5V and can deliver up to 1.5A of continuous current. The device is housed in a compact 12-pin VQFN-HR package measuring 2mm x 2.5mm, making it ideal for space-constrained applications. The TPS2121RUXR features automatic switchover between primary and secondary power sources with minimal dropout voltage and fast transient response, ensuring uninterrupted power to critical loads.
