It accepts a 3.5V to 36V input and delivers up to 3A with a programmable output voltage fixed at 1V or 3.3V. ## Key ratings and what they mean for the BOM The 3.5V minimum input covers cold-crank conditions on a 12V automotive bus, while the 36V maximum handles load-dump transients without external clamping. The 3A continuous output is sized for powering sensor clusters, CAN transceiver rails, or a small MCU core supply. ## Lifecycle and sourcing reality No NRND or EOL notice is on record, so it remains qualified for new designs and volume builds. ROHS3 compliance is already in place, so no additional exemption paperwork is needed for EU-market builds.","metaTitle":"MAX20003ATPB/V+T Automotive Buck Converter, 3A, 20-TQFN","metaDescription":"MAX20003ATPB/V+T is an AEC-Q100 qualified step-down buck converter from Maxim Integrated. 3.5V-36V input, 3A output, 220kHz-2.2MHz switching.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Programmable (Fixed)","Mounting Type":"Surface Mount","Package / Case":"20-WQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"3A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"220kHz ~ 2.2MHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"36V","Voltage - Input (Min)":"3.5V","Voltage - Output (Max)":"10V","Supplier Device Package":"20-TQFN (5x5)","Voltage - Output (Min/Fixed)":"1V (3.3V)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.04","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.04000","currency":"USD"},{"qty":10,"price":"$6.36200","currency":"USD"},{"qty":25,"price":"$6.06640","currency":"USD"},{"qty":100,"price":"$5.26760","currency":"USD"},{"qty":250,"price":"$5.03080","currency":"USD"},{"qty":500,"price":"$4.58692","currency":"USD"},{"qty":1000,"price":"$3.99506","currency":"USD"},{"qty":2500,"price":"$3.84709","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5853b6e3b4a062018df787947e779930.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX20003ATPB/V+T meet AEC-Q100 automotive qualification?","answer":"Yes, the MAX20003ATPB/V+T is part of the Automotive, AEC-Q100 series, meaning it is qualified for automotive-grade reliability and temperature requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX20003ATPB-VT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX20003ATPB-VT when reusing this data.
