TPS40428RHAT TI PMBus Controller | 40-VQFN (6x6) | Dual Output, 600kHz

Product Overview

The TPS40428RHAT from Texas Instruments is a dual-output, synchronous buck controller with PMBus interface, designed for high-current, non-isolated DC/DC conversion. Housed in a compact 40-pin VQFN (6x6 mm) package, it integrates a PMBus-compatible digital interface for real-time monitoring and control. The device operates from a 4.5V to 20V input voltage range and provides two independent outputs with programmable output voltages from 0.6V to 5.5V. With a switching frequency up to 600kHz, it enables high-density power solutions for telecom, networking, and industrial applications.
