The 5 A switch rating means it can supply enough current for USB OTG power or a small LED driver from a single Li-ion cell. ## Input voltage range — what cells fit With a minimum input of 2.3 V and a maximum of 4.85 V, this part works from two alkaline cells in series (2.4 V nominal) or a single lithium-ion cell (3.0 V to 4.2 V). The 2.3 V floor means it can squeeze usable energy out of a nearly depleted Li-ion cell before the undervoltage lockout kicks in. ## Programmable output — setting the rail The output is programmable from 2.85 V up to 4.4 V via an external resistor divider. That covers 3.3 V logic rails, 3.6 V for some RF loads, and 4.2 V for charging a single Li-ion cell. The synchronous rectifier helps maintain efficiency across this range. The 16-DSBGA package measures 1.67 x 1.67 mm — very small, which is great for compact designs but means a hot-air rework station with a fine nozzle and a steady hand are needed for board-level repair. The 0.5 mm pitch BGA pads are not something you want to hand-solder with an iron.","metaTitle":"TPS61280DYFFR Boost Converter, 2.3-4.85V Input, 5A Switch","metaDescription":"Texas Instruments TPS61280DYFFR step-up boost converter, 2.3V to 4.85V input, programmable output 2.85V to 4.4V, 5A switch, 2.3MHz, 16-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":"Programmable","Mounting Type":"Surface Mount","Package / Case":"16-UFBGA, DSBGA","Product Status":"Active","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":"$0.6930","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6c4bb36e960eb43f918b51e1e40b3943.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61280DYFFR/alternatives.json"},"ai":{"faq":[{"question":"What output voltage can TPS61280DYFFR be programmed to?","answer":"Common rails like 3.3 V and 3.6 V are within range."},{"question":"Can TPS61280DYFFR be used for USB OTG applications?","answer":"Yes.
