TPS40428RHAR TI PMBus Controller | 40-VQFN (6x6) | Dual Output, 600kHz

Product Overview

The TPS40428RHAR from Texas Instruments is a dual-output, synchronous buck controller with PMBus interface, designed for high-current, point-of-load (POL) applications. It operates from a 4.5V to 20V input voltage range and provides two independent outputs with adjustable voltage from 0.6V to 5.5V. The device integrates high-side and low-side MOSFET drivers, supports frequency synchronization up to 1MHz, and features programmable soft-start, overcurrent protection, and thermal shutdown. Housed in a compact 40-pin VQFN (6x6 mm) package, it is ideal for space-constrained designs requiring precise voltage regulation and telemetry.
