3 A automotive point-of-load buck
The TPS62813QWRWYRQ1 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 inductor sizing
At 2.2 MHz a 0.47 µH inductor will handle the ripple current; at 1.8 MHz the same ripple requires roughly 0.68 µH.
125°C junction and AEC-Q100 qualification
That covers under-hood and engine-bay environments where ambient temperatures push above 105°C. The 9-VFQFN-HR package with wettable flanks supports automated optical inspection (AOI) of the solder joints, a requirement in high-reliability automotive production lines.
