TPS54294RSAR TI Dual Buck Converter | 16-QFN(4x4) | 4.5-18V, 2A/2A

Product Overview

The TPS54294RSAR is a dual, adaptive on-time D-CAP2™ mode synchronous buck converter from Texas Instruments. It integrates two 2A output current channels in a compact 16-pin QFN (4x4 mm) package. The device operates from a 4.5V to 18V input voltage range and provides adjustable output voltages down to 0.76V with high efficiency. The D-CAP2™ control mode enables fast transient response and simplifies external compensation, making it ideal for space-constrained power supply designs.
