125°C junction — no derating guesswork
The 1A output is continuous across that range, not a room-temperature peak.
1.8–4 MHz switching — trade efficiency for inductor size
Run it at the low end for best efficiency in a thermally constrained module; push it to 4 MHz to shrink the inductor footprint to a 2x2.5 mm or smaller package.
Wettable flank QFN — AOI-friendly
The 9-VFQFN-HR (3x2 mm) package includes wettable flanks on the side pads, so an automated optical inspection system can verify solder joint wetting after reflow. That is a production-line requirement for most automotive Tier-1s — without it, the assembler needs X-ray or a manual inspection step.
