A 4MHz operation lets you use a smaller inductor — typically in the 0.47 µH to 1 µH range — which shrinks the PCB footprint, but the trade-off is higher switching losses that eat into the thermal budget at full load. At the lower end of the frequency range, efficiency improves at the cost of a larger inductor. Housed in a 9-VFQFN-HR package measuring 3 mm x 2 mm with wettable flanks, this part supports automated optical inspection (AOI) of the solder joints after reflow — a requirement for automotive production lines that cannot rely on X-ray alone.","metaTitle":"TPS6281008QWRWYRQ1 Automotive Buck Converter, 4A, AEC-Q100","metaDescription":"Texas Instruments TPS6281008QWRWYRQ1 is an AEC-Q100 qualified step-down buck converter with 4A output, 2.75V-6V input, 1.8-4MHz switching.
