It accepts a 3.9V to 36V input range, covering nominal 12V and 24V automotive buses with headroom for load-dump transients. The adjustable output version lets you set the rail anywhere between a 3.3V minimum and 10V maximum, making it a single-device solution for ECU sub-rails, sensor supplies, and infotainment power trees. ## Switching at 2.1 MHz — inductor size and EMI The 2.1MHz switching frequency lets you use a physically smaller inductor (typically 2.2 µH to 4.7 µH range) compared to 400 kHz parts, which matters when board space is tight inside a 22-VQFN footprint. The synchronous rectifier improves efficiency at moderate loads and eliminates the external Schottky diode. At this frequency, layout discipline on the switch node is critical — keep the loop from the input cap through the IC to the inductor short. ## Temperature range and package The 22-VQFN-HR (5x4 mm) package with wettable flank enables automated optical inspection (AOI) of the solder joints, a requirement in automotive production lines. ## Active lifecycle — no LTB concern For production programs that need multi-year supply assurance, this part carries no imminent obsolescence risk.","metaTitle":"LMS3635MQURNLRQ1 Buck Regulator, 3.5A, AEC-Q100","metaDescription":"TI LMS3635MQURNLRQ1 automotive step-down regulator, 3.5A output, 2.1MHz switching, 3.9V-36V input, 22-VQFN.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"22-VFQFN","lifecycle_stage":"eol_hot","Current - Output":"3.5A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"2.1MHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"36V","Voltage - Input (Min)":"3.9V","Voltage - Output (Max)":"10V","Supplier Device Package":"22-VQFN-HR (5x4)","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.91","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.91000","currency":"USD"},{"qty":10,"price":"$5.30500","currency":"USD"},{"qty":25,"price":"$5.01560","currency":"USD"},{"qty":100,"price":"$4.34670","currency":"USD"},{"qty":250,"price":"$4.12376","currency":"USD"},{"qty":500,"price":"$3.70026","currency":"USD"},{"qty":1000,"price":"$3.12070","currency":"USD"},{"qty":3000,"price":"$2.96466","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/eedb24611624f264142d197cd5f88240.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output current of LMS3635MQURNLRQ1?","answer":"It delivers 3.5A continuous output current from a single adjustable output rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMS3635MQURNLRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LMS3635MQURNLRQ1 when reusing this data.
