It accepts an input from 2.3V to 6V and delivers an adjustable output up to 18.5V, making it a fit for powering displays, sensor bias rails, and auxiliary supplies in vehicle electronics. ## Pin-selectable switching frequency: 650 kHz or 1.2 MHz A single pin selects between 650 kHz and 1.2 MHz switching frequency. At 1.2 MHz the converter runs a smaller inductor and ceramic output capacitor, saving board area. Dropping to 650 kHz improves efficiency by reducing switching losses — useful when the load current is light or the thermal budget is tight. The part does not include a synchronous rectifier, so the external Schottky diode must handle the peak inductor current plus a margin for the output short-circuit condition. The 2A switch rating sets the practical output current ceiling at roughly 1.5A for a 5V output from a 3.3V rail, depending on the inductor and diode chosen.","metaTitle":"TPS61085ATDGKRQ1 Automotive Boost Converter, 2A Switch","metaDescription":"Texas Instruments TPS61085ATDGKRQ1 AEC-Q100 boost converter, 2.3V-6V input, 2A switch, 650kHz/1.2MHz switching frequency, -40°C to 125°C junction temp, 8-VSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","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~125°C(TJ)","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":"$2.9600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ab3bf5d95cad9c61fad9c7f9f6c909fc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61085ATDGKRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS61085ATDGKRQ1 AEC-Q100 qualified?","answer":"Yes, it is listed under the Automotive, AEC-Q100 series.
