Product details

Dual-Channel Buck for Automotive Rails

It operates from a 2.75V to 6V input rail and delivers two adjustable outputs with current ratings of 1A, 2A, 2A, and 3A across the two channels. Switching frequency is programmable from 1.8MHz to 4MHz, allowing the PCB layout engineer to select inductor values in the 0.47µH to 2.2µH range and keep the ripple within the output capacitor's ESR budget.

AEC-Q100 Grade and Temperature Range

Lifecycle status is Active. The part is ROHS3 compliant.

Package and Mounting Checklist

Supplied in a 14-VQFN-HR package (2.3mm x 2.7mm body) with wettable flanks for automated optical inspection (AOI) after reflow. The exposed thermal pad must be connected to the ground plane with a thermal via array to keep the junction temperature below the 125°C limit under full load.

The base product number is TPS62442.

Frequently asked questions

Can TPS62442QWRQRRQ1 be used in battery-powered applications?

Yes. The 2.75V minimum input voltage allows operation from a single-cell Li-ion battery through its discharge range. The synchronous rectifier maintains efficiency above 90% across most of the load range, which matters for extending battery run time in portable automotive test equipment or auxiliary power modules.
