The single output is positive-configuration; the 400 mA rating is the continuous current limit, so the load budget and PCB trace width should be sized for derating at elevated ambient temperatures. No stock-holding claim — quoted per order. ## 10-SON (2.5x2.5) — compact footprint, exposed-pad thermal path Housed in a 10-WFDFN exposed-pad package (2.5x2.5 mm body), the TPS63900DSKR is a surface-mount part.","metaTitle":"TI TPS63900DSKR Buck-Boost Converter, 400 mA","metaDescription":"Texas Instruments TPS63900DSKR step-up/step-down buck-boost converter. 1.8 V to 5.5 V input, 400 mA output, synchronous rectification, -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":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up/Step-Down","Topology":"Buck-Boost","Output Type":"Programmable","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"400mA","Number of Outputs":"1","Base Product Number":"TPS63900","Output Configuration":"Positive","Frequency - Switching":"-","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"1.8V","Voltage - Output (Max)":"5V","Supplier Device Package":"10-SON (2.5x2.5)","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.48884","priceTiers":[{"qty":1,"price":"$1.48884","currency":"USD"},{"qty":10,"price":"$1.31715","currency":"USD"},{"qty":30,"price":"$1.15322","currency":"USD"},{"qty":100,"price":"$1.03231","currency":"USD"},{"qty":500,"price":"$0.98356","currency":"USD"},{"qty":1000,"price":"$0.95811","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/53742115df1c8aea3ec7383992f63a3d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS63900DSKR/alternatives.json"},"ai":{"faq":[{"question":"Does TPS63900DSKR have under-voltage lockout?","answer":"The evidence does not list under-voltage lockout as a separate feature.
