TPS2540ARTET TI USB Power Switch | 16-WQFN (3X3) | 2.7A, 4.5-5.5V

Product Overview

The TPS2540ARTET from Texas Instruments is a high-performance USB power switch designed for applications requiring precise current limiting and thermal protection. Housed in a compact 16-WQFN (3x3 mm) package, this device integrates a 2.7A current-limited power switch with a programmable current limit, making it ideal for USB ports and other power distribution systems. It operates over an input voltage range of 4.5V to 5.5V, ensuring compatibility with standard USB power rails. The TPS2540ARTET features a low on-resistance (typically 70 mΩ) to minimize power loss and supports fast transient response for stable output under varying loads.
