It delivers 2A continuous from a 2.75V to 6V input, with an adjustable output from 0.6V up to 5.5V. The 1.8MHz to 4MHz switching frequency range lets you push the inductor size down when board area is tight, or drop the frequency to improve light-load efficiency. ## Wettable-flank QFN — inspection without X-ray The 9-VFQFN package (3x2 mm body) uses wettable-flank terminations. That means the side of each pad wets with solder during reflow, so an automated optical inspection (AOI) system can verify the joint — no X-ray needed. For automotive production lines that require 100% solder-joint inspection, this saves a process step. The package is surface-mount with wettable flank, specified as 9-VQFN-HR. The base product number is TPS6281220, so any PCN or documentation updates track under that root.","metaTitle":"TPS6281220QWRWYRQ1 Automotive Buck Converter, 2A, AEC-Q100","metaDescription":"Texas Instruments TPS6281220QWRWYRQ1 automotive step-down converter, 2.75V-6V input, 0.6V-5.5V adjustable output, 2A, 1.8-4MHz, -40°C to 125°C, 9-VFQFN","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":"2A","Number of Outputs":"1","Base Product Number":"TPS6281220","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":"$2.6400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/48130765433ddea195ad000d60f116ea.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS6281220QWRWYRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is the TPS6281220QWRWYRQ1 AEC-Q100 qualified?","answer":"Yes, it is listed under the Automotive, AEC-Q100 series.
