TPS542951RSAR TI DC-DC Converter | 16-QFN (4x4) | 4.5V-18V Input, 2A Output

Product Overview

The TPS542951RSAR from Texas Instruments is a high-efficiency, synchronous step-down DC-DC converter designed for a wide range of applications. It integrates a 2A, 0.1Ω high-side MOSFET and a 0.1Ω low-side MOSFET, enabling compact power solutions. The device operates from a 4.5V to 18V input voltage range and provides an adjustable output voltage down to 0.8V. With a switching frequency of 700kHz, it allows for small external components. The TPS542951RSAR is available in a 16-pin QFN (4x4mm) package, making it ideal for space-constrained designs.
