The fixed 1.1 V output targets core and I/O supplies in automotive ECU, ADAS sensor modules, and infotainment power trees where the ambient under the dashboard or behind the head unit can push past 85 °C. ## Switching frequency range and output set point The switching frequency spans 1.8 MHz to 4 MHz, letting the designer trade off inductor size against efficiency — 1.8 MHz keeps switching losses lower for a 12 V battery-derived rail, while 4 MHz shrinks the magnetics for space-constrained camera or radar modules. Output is fixed at 1.1 V, so no external feedback divider is needed; the internal compensation is tuned for that set point. ## AEC-Q100 and the 125 °C operating window ## Package and footprint for production The 9-VFQFN-HR (3x2 mm) package with wettable flanks supports automated optical inspection (AOI) of the solder joints — a requirement for automotive production lines that cannot rely on x-ray sampling alone. The small footprint leaves room for the input and output caps close to the IC, which is critical for keeping the switching loop tight at 4 MHz.","metaTitle":"TPS6281208QWRWYRQ1 Automotive Buck Converter, 2 A, 9-VFQFN","metaDescription":"Texas Instruments TPS6281208QWRWYRQ1 automotive step-down buck converter, AEC-Q100 qualified, 2 A output, fixed 1.1 V, 1.8-4 MHz switching, -40 to 125 °C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"9-VFQFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"2A","Number of Outputs":"1","Base Product Number":"TPS6281208","Output Configuration":"Positive","Frequency - Switching":"1.8MHz ~ 4MHz","Operating Temperature":"-40°C~125°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.75V","Voltage - Output (Max)":"-","Supplier Device Package":"9-VQFN-HR (3x2)","Voltage - Output (Min/Fixed)":"1.1V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/48130765433ddea195ad000d60f116ea.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS6281208QWRWYRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS6281208QWRWYRQ1 suitable for automotive applications?","answer":"Yes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS6281208QWRWYRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS6281208QWRWYRQ1 when reusing this data.
