It is designed for point-of-load regulation in automotive ECUs, ADAS sensors, and infotainment systems where the ambient temperature under the hood or inside the cabin can reach 125°C junction. ## Switching frequency and inductor sizing The 1.8MHz to 4MHz switching frequency range lets the designer trade off efficiency against inductor size. At 4MHz the external inductor can drop to 0.47 µH or 1.0 µH, shrinking the total solution footprint for space-constrained automotive modules. ## Wettable flank package for AOI The 9-VFQFN-HR (3x2 mm) package with wettable flanks allows automated optical inspection of the solder joints after reflow — a requirement in many automotive production lines. The surface-mount, wettable-flank package sits flat on the PCB and the exposed pad provides a low thermal impedance path to the board copper.","metaTitle":"TPS628100MQWRWYRQ1 Automotive Buck Converter, 4A, AEC-Q100","metaDescription":"Texas Instruments TPS628100MQWRWYRQ1 step-down buck converter, 4A output, 2.75V-6V input, AEC-Q100 qualified, -40°C 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":"4A","Number of Outputs":"1","Base Product Number":"TPS628100","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)":"-","Supplier Device Package":"9-VQFN-HR (3x2)","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/851fc6440336a3f26e38460cff48b8ca.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS628100MQWRWYRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS628100MQWRWYRQ1 pin compatible with other buck converters?","answer":"Pin compatibility depends on the specific alternate part's package and pinout.
