It accepts an input from 2.3 V to 4.85 V and delivers a programmable output between 2.85 V and 4.4 V at a fixed 2.3 MHz switching frequency. ## Input and output voltage boundaries The 2.3 V minimum input suits single-cell Li-ion or two-cell alkaline applications; the 4.85 V maximum input covers USB and regulated 5 V rails. The programmable output range tops out at 4.4 V, so this part cannot deliver a regulated 5 V output — designs requiring 5 V need a different boost topology or a SEPIC. The 2.3 MHz switching frequency allows small inductor and capacitor values. ## Sourcing reality: obsolete, sourced to order Availability is limited to independent-distribution stock and surplus channel inventory.","metaTitle":"TPS61281AYFFR Boost Converter, 5A Switch, 2.3 MHz, Obsolete","metaDescription":"Texas Instruments TPS61281AYFFR step-up boost converter, 2.3V-4.85V input, programmable 2.85V-4.4V output, 5A switch.","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":"TPS61281","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/TPS61281AYFFR/alternatives.json"},"ai":{"faq":[{"question":"Can TPS61281AYFFR be used in a 5V output design?","answer":"No. The maximum programmable output voltage is 4.4 V, so a 5 V output is outside the part's specification."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS61281AYFFR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS61281AYFFR when reusing this data.
