TPS40425RHAT TI PMBus Controller | 40-VQFN (6x6) | Dual Output, 600kHz

Product Overview

The TPS40425RHAT from Texas Instruments is a dual-output, synchronous buck controller with PMBus interface, designed for high-density power conversion. It 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. The device integrates high-side and low-side MOSFET drivers and supports up to 600kHz switching frequency. Housed in a compact 40-pin VQFN (6x6mm) package, it is ideal for space-constrained applications requiring precise voltage regulation and telemetry.
