TPS40422RSBR TI Power Management IC | 40-WQFN (5x5) | Dual Output, PMBus

Product Overview

The TPS40422RSBR 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 programmable output voltages from 0.6V to 5.5V. The device integrates high-side and low-side MOSFET drivers and supports adaptive dead-time control for high efficiency. Housed in a compact 40-pin WQFN (5x5 mm) package, it is ideal for space-constrained designs requiring precise voltage regulation and telemetry.
