The output is adjustable via a resistor divider from a 20 V floor to an 85 V ceiling. That 85 V maximum means the switching node rings to roughly the same voltage — layout needs a tight power loop from the inductor through the diode to the output capacitor, with the exposed pad (16-WQFN, 3x3 mm) soldered to a copper plane for thermal relief.","metaTitle":"TPS61390RTET Texas Instruments Boost Converter, 85 V Output","metaDescription":"Texas Instruments TPS61390RTET step-up boost converter, 2.5 V to 5.5 V input, adjustable output to 85 V, 700 kHz switching, Active production, 16-WQFN (3x3 mm).","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"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":"16-WFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"-","Number of Outputs":"1","Base Product Number":"TPS61390","Output Configuration":"Positive","Frequency - Switching":"700kHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"No","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.5V","Voltage - Output (Max)":"85V","Supplier Device Package":"16-WQFN (3x3)","Voltage - Output (Min/Fixed)":"20V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.4500","priceTiers":[{"qty":1,"price":"$4.45000","currency":"USD"},{"qty":10,"price":"$3.99600","currency":"USD"},{"qty":25,"price":"$3.77800","currency":"USD"},{"qty":100,"price":"$3.27410","currency":"USD"},{"qty":250,"price":"$3.10624","currency":"USD"},{"qty":500,"price":"$2.78720","currency":"USD"},{"qty":1250,"price":"$2.37600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a6a0825ffd7a6320fb611b8a9ce871ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61390RTET/alternatives.json"},"ai":{"faq":[{"question":"Can TPS61390RTET be used for a 3.3 V output?","answer":"No — the minimum adjustable output is 20 V, so this part cannot produce a 3.3 V rail.
