The integrated switch is rated for 2.4 A, which sets the maximum deliverable output current at 5 V — typically around 1 A depending on the input voltage and efficiency. ## What the 2.4 A switch rating means for your BOM The 2.4 A switch current is the peak current the internal FET can handle cycle-by-cycle. For a boost converter, the input current is higher than the output current, so a 2.4 A switch limits the output to roughly 1 A at 5 V from a 3.3 V input, assuming 85% efficiency. If your load pulls 1.2 A at 5 V, this part will current-limit or drop out — size up to the TPS61258 or add a second stage. The fixed 5 V output means no external feedback divider, saving two resistors and one feedback node on the layout. ## Package and layout: 9-DSBGA Not a hand-solder part — you need a pick-and-place and a reflow oven. It works in outdoor IoT gateways, portable instruments, battery-powered sensors, and any device that sees a parking lot in winter or a hot enclosure in summer. Not qualified to AEC-Q100, so skip it for under-hood or chassis-mounted automotive designs unless you plan your own qualification.","metaTitle":"TPS61256YFFR Boost Converter, 5V Fixed Output, 2.4A Switch","metaDescription":"TI TPS61256YFFR step-up boost converter with fixed 5V output, 2.4A switch current, 3.5MHz switching, -40°C to 85°C, 9-DSBGA.","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","Topology":"Boost","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"9-UFBGA, DSBGA","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"2.4A (Switch)","Number of Outputs":"1","Base Product Number":"TPS61256","Output Configuration":"Positive","Frequency - Switching":"3.5MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"4.85V","Voltage - Input (Min)":"2.5V","Voltage - Output (Max)":"-","Supplier Device Package":"9-DSBGA","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fb1f256fd0f2a9af25dea522850f97ea.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61256YFFR/alternatives.json"},"ai":{"faq":[{"question":"Can TPS61256YFFR be used in portable devices?","answer":"Yes.
