PWM dimming is supported directly, giving firmware control over brightness without an external dimming signal generator. For BOM lines already qualified to this regulator, the only procurement path is the surplus and broker market. We source LM3502SQX-25/NOPB against an RFQ, confirming date-code provenance and device authenticity before shipment. Surface-mount assembly follows standard lead-free reflow profiles.","metaTitle":"LM3502SQX-25/NOPB DC-DC Boost Regulator, 25 V Output","metaDescription":"Texas Instruments LM3502SQX-25/NOPB is a 1 MHz PWM-dimming boost regulator for backlight, 25 V max output, 2 channels, 600 mA switch.","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%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Does LM3502SQX-25/NOPB support PWM dimming?","answer":"Yes, PWM dimming is a listed feature.
