The high-frequency range keeps switching noise above the AM band and allows the use of small, low-profile inductors. ## Thermal and package considerations The 9-VFQFN-HR (3x2 mm) package with wettable flanks supports automated optical inspection (AOI) of the solder joints.","metaTitle":"TPS6281120QWRWYRQ1 Automotive Buck Converter, 1 A, 9-VFQFN","metaDescription":"TI TPS6281120QWRWYRQ1 AEC-Q100 step-down regulator, 2.75 V to 6 V input, adjustable output, 1.8-4 MHz switching, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"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":"1A","Number of Outputs":"1","Base Product Number":"TPS6281120","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)":"5.5V","Supplier Device Package":"9-VQFN-HR (3x2)","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/48130765433ddea195ad000d60f116ea.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS6281120QWRWYRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS6281120QWRWYRQ1 pin-compatible with the base TPS6281120?","answer":"The base product number TPS6281120 shares the same pinout and package footprint.
