Product details

3 A automotive buck in a 3×2 mm wettable-flank QFN

The TPS6281320QWRWYRQ1 is a Texas Instruments automotive-grade synchronous step-down converter rated for 3 A continuous output from a 2.75 V to 6 V input rail.

Switching frequency and thermal budget

Switching frequency is programmable from 1.8 MHz to 4 MHz, letting the designer trade off inductor size against switching losses. The 9-VFQFN (3x2) package with exposed pad and wettable flank terminals keeps the thermal path through the PCB copper pour; junction temperature is rated to 125°C, matching the under-hood ambient profile.

AEC-Q100 and production status

The wettable flank package supports automated solder-joint inspection per automotive quality standards.

Frequently asked questions

What is the output current rating of TPS6281320QWRWYRQ1?

The device is rated for 3 A continuous output current.

What are the differences between TPS6281320QWRWYRQ1 and TPS6281320?

The TPS6281320QWRWYRQ1 is the automotive AEC-Q100 qualified variant of the base TPS6281320. The base part number shares the same electrical specification; the QWRWYRQ1 suffix denotes the automotive-grade, wettable-flank package and tape-and-reel delivery.
