It integrates the switching FET (rated 600mA switch current) and drives two independent LED strings with PWM dimming control. The 1 MHz switching frequency allows the use of small inductors and ceramic capacitors, keeping the total solution footprint compact — a fit for space-constrained LCD backlight supplies in portable instruments or industrial panels. It is no longer available through the factory or authorized distributors for new orders. No official replacement or successor part number is recorded in the lifecycle data. For a drop-in alternative, the buyer should verify pin compatibility and electrical ratings against the original BOM — the LM3502 family shares the same base number, but the specific output voltage and package variant must match.","metaTitle":"LM3502SQX-25 DC-DC Boost Regulator, 25V Output, 1MHz","metaDescription":"LM3502SQX-25 is a 25V output boost regulator with PWM dimming, 600mA switch, 2 outputs, 1MHz.","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)","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":"25V","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":"600mA (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/LM3502SQX-25/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3502SQX-25?","answer":"No official replacement part number is recorded in the lifecycle data for the LM3502SQX-25.
