Two independent outputs support dual LED strings or split backlight zones, each capable of sourcing up to 750 mA (switch current limit). PWM dimming is used to control LED brightness, compatible with common backlight controller interfaces. ## Obsolete — sourcing via independent distribution For existing BOM lines, procurement must go through independent distribution or surplus channels.","metaTitle":"LM3502SQ-44 DC-DC Regulator, 44V Boost, 1MHz, 16-WQFN","metaDescription":"LM3502SQ-44 DC-DC regulator, step-up boost topology, 44V output, 1MHz switching, PWM dimming, 16-WFQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"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":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Output":"44V","Number of Outputs":"2","Internal Switch(s)":"Yes","Base Product Number":"LM3502","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"5.5V","Voltage - Supply (Min)":"2.5V","Supplier Device Package":"16-WQFN (4x4)","Current - Output / Channel":"750mA (Switch)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a1b4525ebe7daa3a039473fa31545909.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3502SQ-44/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3502SQ-44","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3502SQ-44 when reusing this data.
