The 1.8 MHz to 4 MHz switching frequency range lets the designer trade inductor size against switching losses — a higher frequency shrinks the magnetics at the cost of increased gate-drive loss and EMI filtering effort. ## Input and output voltage boundaries The positive output configuration and the absence of a synchronous rectifier mean the low-side switch is external or the diode is used — check the application circuit for the intended topology. ## 9-VFQFN with wettable flanks Housed in a 9-pin VFQFN measuring 3 mm x 2 mm (supplier device package 9-VQFN-HR), the part uses a wettable-flank surface-mount termination. The wettable flank enables automated optical inspection (AOI) of the solder joints — a requirement for automotive production lines that cannot rely on hidden solder joints under the package.","metaTitle":"TPS6281020QWRWYRQ1 Automotive Buck Converter, 4 A, 9-VFQFN","metaDescription":"Texas Instruments TPS6281020QWRWYRQ1 automotive step-down converter, AEC-Q100 qualified, 4 A output, 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":"Adjustable","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"9-VFQFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"4A","Number of Outputs":"1","Base Product Number":"TPS6281020","Output Configuration":"Positive","Frequency - Switching":"1.8MHz ~ 4MHz","Operating Temperature":"-40°C~125°C(TA)","Synchronous Rectifier":"No","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/addc9596b062c19f4b98f3ab12cad75c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS6281020QWRWYRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS6281020QWRWYRQ1 AEC-Q100 qualified for automotive?","answer":"Yes, the series is listed as Automotive, AEC-Q100.
