UCC39421PWTR TI DC-DC Controller | 16-TSSOP | 1.8V-8V Input, 1A Output

Product Overview

The UCC39421PWTR from Texas Instruments is a high-performance, low-power DC-DC controller designed for step-down (buck) regulation. It operates from an input voltage range of 1.8V to 8V and delivers up to 1A output current. Housed in a compact 16-TSSOP package, this device integrates a synchronous rectifier driver for high efficiency, making it ideal for portable and battery-powered applications. The controller features a fixed 1.5MHz switching frequency, allowing for small external components and reduced solution size. With its low quiescent current of 30µA, it extends battery life in standby modes.
