The 9-VFQFN (3x2) package with exposed pad and wettable flank terminals keeps the thermal path through the PCB copper pour; junction temperature is rated to 125°C, matching the under-hood ambient profile. ## AEC-Q100 and production status The wettable flank package supports automated solder-joint inspection per automotive quality standards.","metaTitle":"TPS6281320QWRWYRQ1 Automotive Buck Converter, 3 A, 9-VFQFN","metaDescription":"Texas Instruments TPS6281320QWRWYRQ1 automotive AEC-Q100 step-down buck converter, 3 A output, 1.8–4 MHz switching, wettable flank 9-VFQFN package.","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":"Adjustable","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"9-VFQFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3A","Number of Outputs":"1","Base Product Number":"TPS6281320","Output Configuration":"Positive","Frequency - Switching":"1.8MHz ~ 4MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.75V","Voltage - Output (Max)":"5.5V","Supplier Device Package":"9-VQFN-HR (3x2)","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0bdc153a9999f917b09e2b491758f7dd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS6281320QWRWYRQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the output current rating of TPS6281320QWRWYRQ1?","answer":"The device is rated for 3 A continuous output current."},{"question":"What are the differences between TPS6281320QWRWYRQ1 and TPS6281320?","answer":"The TPS6281320QWRWYRQ1 is the automotive AEC-Q100 qualified variant of the base TPS6281320.
