The switching frequency spans 4 Hz to 2 MHz, which lets the designer tune for efficiency at light load or shrink the inductor at higher switching rates. ## 400 mA output in a 1.46 × 1.11 mm DSBGA The 12-DSBGA package (1.46 × 1.11 mm) is the smallest footprint for a 400 mA buck-boost in TI's portfolio—critical when board real estate is the constraint, as in wearable or IoT sensor nodes. Compared to the LMR33630APCQRNXRQ1, a 3 A buck converter in a larger package, the TPS63901YCJR trades output current for a much smaller solution size and the ability to both step up and step down from a single battery cell. ## Active production — no end-of-life watch ## Design-in checklist for the DSBGA footprint The 12-XFBGA DSBGA package requires a PCB fab capable of via-in-pad or microvia fan-out for routing supply and output traces. Input voltage range from 1.8 V to 5.5 V covers a single Li-ion cell (3.0 V to 4.2 V) and standard 3.3 V or 5 V rails, so no pre-regulator is needed in most battery-powered designs.","metaTitle":"TPS63901YCJR Buck-Boost Regulator","metaDescription":"Texas Instruments TPS63901YCJR step-up/step-down regulator, 1.8 V to 5.5 V input, 400 mA output, programmable output, synchronous rectification, -40°C to","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"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":"12-XFBGA, DSBGA","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"400mA","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"4Hz ~ 2MHz","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":"12-DSBGA (1.46x1.11)","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3800","priceTiers":[{"qty":1,"price":"$2.38000","currency":"USD"},{"qty":10,"price":"$2.14100","currency":"USD"},{"qty":25,"price":"$2.02000","currency":"USD"},{"qty":100,"price":"$1.72100","currency":"USD"},{"qty":250,"price":"$1.61600","currency":"USD"},{"qty":500,"price":"$1.41400","currency":"USD"},{"qty":1000,"price":"$1.17160","currency":"USD"},{"qty":3000,"price":"$1.09080","currency":"USD"},{"qty":6000,"price":"$1.05040","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/57fa18c9e8f4ed0d0acdc1f820075217.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS63901YCJR/alternatives.json"},"ai":{"faq":[{"question":"Can TPS63901YCJR boost 3.3 V to 5 V?","answer":"Yes.
