TPS54494PWP TI Dual Synchronous Step-Down Converter | 16-HTSSOP | 4.5V-18V Input, 4A Output

Product Overview

The TPS54494PWP from Texas Instruments is a dual, adaptive on-time D-CAP2™ mode synchronous buck converter. It integrates two independent step-down converters capable of delivering up to 4A continuous output current per channel. The device operates from a 4.5V to 18V input supply and provides output voltages as low as 0.76V. Housed in a 16-pin HTSSOP (PWP) package with PowerPAD™ for enhanced thermal performance, it is designed for space-constrained, high-efficiency power solutions.
