At 4 MHz the inductor can drop below 1 µH, shrinking the footprint for space-constrained automotive modules. The AEC-Q100 qualification adds the stress-tested reliability required for automotive production lines — no additional screening needed for Tier-1 builds. ## 9-VFQFN-HR with wettable flank Packaged in a 9-pin VFQFN-HR measuring 3 mm × 2 mm, with wettable flank terminals. The wettable flank allows automated optical inspection (AOI) of the solder joints after reflow — a requirement for automotive-quality QFN assembly that standard smooth-side QFNs cannot meet.","metaTitle":"TPS6281126QWRWYRQ1 Automotive Buck Regulator, 1A, AEC-Q100","metaDescription":"TI TPS6281126QWRWYRQ1 step-down DC-DC converter, 1A output, 2.75-6V input, 1.8-4MHz switching, -40 to 125°C, AEC-Q100 qualified.
