The input supply range spans 4.5 V to 24 V, covering common rails from 5 V USB to 12 V or 24 V industrial supplies. Surface-mount reflow with a standard lead-free profile applies; no special moisture sensitivity level is flagged in the listing, but the QFN package benefits from a pre-bake if the reel seal is broken.","metaTitle":"TPS61181ARTER DC-DC Boost Regulator, 6-Channel LED Driver","metaDescription":"Texas Instruments TPS61181ARTER: DC-DC step-up regulator, 6 outputs, 30 mA per channel, 38 V max, PWM dimming, -40°C to 85°C, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Type":"DC DC Regulator","Series":"-","Dimming":"PWM","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Up (Boost)","Frequency":"1MHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"16-WFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Output":"38V","Number of Outputs":"6","Internal Switch(s)":"Yes","Base Product Number":"TPS61181","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"24V","Voltage - Supply (Min)":"4.5V","Supplier Device Package":"16-WQFN (3x3)","Current - Output / Channel":"30mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7875","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/208e6bce6ce3bfdfc36bbf2772b7b9a0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61181ARTER/alternatives.json"},"ai":{"faq":[{"question":"Is TPS61181ARTER obsolete or end-of-life?","answer":"No."},{"question":"What is the maximum number of LEDs the TPS61181ARTER can support?","answer":"The TPS61181ARTER drives up to six LED strings, each at up to 30 mA. The maximum number of LEDs per string depends on the forward voltage of the LEDs and the 38 V output ceiling — typically 8 to 10 white LEDs in series per string, assuming a 3 V forward drop each."},{"question":"Is TPS61181ARTER compatible with a 3.3 V input?","answer":"No. The minimum supply voltage is 4.5 V. A 3.3 V rail is below the operating range; a boost converter would need to be powered from a higher-voltage supply or a separate 5 V rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS61181ARTER","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS61181ARTER when reusing this data.
