The wide input covers cold-crank and load-dump conditions on a 12 V or 24 V automotive bus without an external pre-regulator. Switching at a fixed 2.2 MHz keeps the inductor and output capacitor small — the 9-VFQFN-HR (2x2) package with wettable flank supports automated optical inspection (AOI) on the assembly line. The output is adjustable from a 1 V reference up to 18 V, with a fixed 3.3 V option on the same die — the MSC3R suffix selects the 3.3 V fixed version. Synchronous rectification is integrated, so no external Schottky diode is needed. ## Grade-0 temperature capability and AEC-Q100 qualification Operating junction temperature spans -40°C to 150°C (TJ), placing it in the AEC-Q100 Grade-0 band — the highest reliability tier for underhood and engine-mounted electronics. Grade-0 qualification means the part passes the full suite of AEC-Q100 stress tests (HTSL, TC, HAST, HTOL) at the 150°C limit, which is the OEM auditor's first check. ## Active lifecycle and sourcing posture For new designs, this part is a first-choice candidate; there is no imminent last-time-buy risk. Available in Tape & Reel (TR) or Cut Tape (CT) packaging for the 9-VFQFN footprint. Sourced through authorized and independent distribution channels; current pricing and lead time are confirmed at RFQ against the BOM quantity.","metaTitle":"LMR43620MSC3RPERQ1 Texas Instruments Buck Converter, 2A","metaDescription":"LMR43620MSC3RPERQ1 Texas Instruments automotive step-down buck converter, 2A output, 3V-36V input, -40°C to 150°C.
