Switching at 340 kHz, the part balances inductor size against switching losses.
It is not AEC-Q100 qualified, so it is not the pick for under-hood or chassis-mounted automotive designs — for that, the LMR33630APCQRNXRQ1 (AEC-Q100, -40°C to 125°C junction) is a closer fit, though it switches at 2.1 MHz and requires a different inductor selection.
For a BOM freeze, this part is a clean line item — no PCN risk from an impending EOL.
