TPS40422RHAR TI Power Management IC | 40-VQFN (6x6) | Dual Output, PMBus

Product Overview

The TPS40422RHAR 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 from 0.6V to 5.5V, each capable of up to 20A with external MOSFETs. The device integrates a PMBus-compatible serial interface for monitoring and control, enabling precise voltage regulation, margining, and fault reporting. Housed in a compact 40-pin VQFN (6x6 mm) package, it is ideal for space-constrained designs requiring high efficiency and flexibility.
