Switching frequency is 2.3 MHz, which allows small inductor values (typically 1 µH to 2.2 µH) and keeps the output ripple within a tight band, but the high frequency also increases switching losses in the pass FET. Output is programmable from a minimum fixed 2.85 V up to 4.4 V, with positive configuration — the feedback divider sets the regulation point. ## Package and temperature — board-fit realities Not a hand-solderable part. Synchronous rectifier built in — improves efficiency at moderate to heavy loads by replacing the freewheeling diode with a low-Rds(on) FET. ## Input voltage range and application fit Input range is 2.3 V to 4.85 V — covers single-cell Li-ion (3.0 V to 4.2 V typical), two-cell alkaline, or a regulated 3.3 V rail. Below 2.3 V the converter does not start; above 4.85 V the input overvoltage protection engages.","metaTitle":"TPS61280AYFFT boost converter, 5A switch, 2.3 MHz, DSBGA","metaDescription":"Texas Instruments TPS61280AYFFT step-up boost converter, 5A switch, 2.3 MHz, programmable output, 16-DSBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up","Topology":"Boost","Output Type":"Programmable","Mounting Type":"Surface Mount","Package / Case":"16-UFBGA, DSBGA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Output":"5A (Switch)","Number of Outputs":"1","Base Product Number":"TPS61280","Output Configuration":"Positive","Frequency - Switching":"2.3MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"4.85V","Voltage - Input (Min)":"2.3V","Voltage - Output (Max)":"4.4V","Supplier Device Package":"16-DSBGA (1.67x1.67)","Voltage - Output (Min/Fixed)":"2.85V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9900","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61280AYFFT/alternatives.json"},"ai":{"faq":[{"question":"What is the output current of TPS61280AYFFT?","answer":"The integrated switch is rated for 5 A.
