TPS40091RHDR TI Power Management IC | 28-VQFN (5x5) | 4.5V-15V Input, 3A Output

Product Overview

The TPS40091RHDR from Texas Instruments is a high-performance, synchronous buck controller designed for low-voltage, high-current power conversion. It operates from an input voltage range of 4.5V to 15V and can deliver output currents up to 3A. The device integrates a high-side and low-side N-channel MOSFET driver, making it ideal for point-of-load (POL) applications. Housed in a compact 28-pin VQFN (5x5 mm) package, it offers excellent thermal performance and space savings.
