The small footprint demands a controlled reflow profile — the datasheet's recommended land pattern and stencil aperture are the starting point for the PCB layout. The synchronous rectifier is integrated, so no external Schottky diode is needed.","metaTitle":"TPS629203QDRLRQ1 Buck Converter, 300 mA, AEC-Q100, SOT-583","metaDescription":"Texas Instruments TPS629203QDRLRQ1 automotive step-down buck converter, 300 mA output, 1/2.5 MHz switching, SOT-583 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","Package / Case":"SOT-583","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"300mA","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"1MHz, 2.5MHz","Operating Temperature":"-40°C~150°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"17V","Voltage - Input (Min)":"3V","Voltage - Output (Max)":"5.5V","Supplier Device Package":"SOT-583","Voltage - Output (Min/Fixed)":"0.4V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9643e5fccd3b658ffdc06da655a04d54.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS629203QDRLRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS629203QDRLRQ1 obsolete?","answer":"No — the product status is listed as Active."},{"question":"What is the output current of TPS629203QDRLRQ1?","answer":"The rated continuous output current is 300 mA.
