That 2 A rating is the peak current the switch can handle, not the output current. ## 650 kHz or 1.2 MHz — the inductor trade-off The switching frequency is pin-selectable between 650 kHz and 1.2 MHz. Running at 1.2 MHz shrinks the inductor footprint but increases switching losses. ## Input and output voltage range The adjustable output goes up to 18.5 V, which opens up applications like biasing LCD panels, driving white LED strings, or powering sensor rails that need more than the input bus. Minimum fixed output starts at 2.8 V.","metaTitle":"TPS61085DGKR Step-Up Boost Converter, 2A Switch, 8-VSSOP","metaDescription":"Texas Instruments TPS61085DGKR step-up boost converter. 2A internal switch, 650kHz/1.2MHz switching frequency, adjustable output to 18.5V.","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":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"2A (Switch)","Number of Outputs":"1","Base Product Number":"TPS61085","Output Configuration":"Positive","Frequency - Switching":"650kHz, 1.2MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"No","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.3V","Voltage - Output (Max)":"18.5V","Supplier Device Package":"8-VSSOP","Voltage - Output (Min/Fixed)":"2.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ade6096d49003e53e07b47a8d2564e9e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61085DGKR/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum output current of TPS61085DGKR?","answer":"The internal switch is rated for 2 A peak current. The maximum continuous output current depends on the input-to-output voltage ratio and efficiency; for a typical 5 V output from a 3.3 V input, you can expect around 1 A to 1.2 A continuous."},{"question":"What is the switching frequency of TPS61085DGKR?","answer":"The switching frequency is pin-selectable: 650 kHz or 1.2 MHz. Use 650 kHz for higher efficiency and 1.2 MHz for smaller inductor size."},{"question":"Is TPS61085DGKR suitable for battery-powered applications?","answer":"Yes. The 2.3 V minimum input voltage lets it run from a single-cell Li-ion battery down to near-depletion, and the selectable switching frequency helps balance efficiency against inductor size in a portable design."},{"question":"Can TPS61085DGKR be used for an LED driver?","answer":"Yes, it can drive a string of white LEDs. The adjustable output goes up to 18.5 V, which is enough for 4-5 series LEDs. You will need external current-sense circuitry since the part does not have a dedicated LED driver constant-current loop."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS61085DGKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS61085DGKR when reusing this data.
