The 400mA switch current rating sets the maximum LED string current — for a typical 3-LED white string at 20 mA per LED, the switch sees roughly 80 mA peak, leaving ample headroom. Above 300 mA total LED current, the inductor saturation rating and PCB copper pour for the switch node need attention. Housed in an 8-bump wafer-level chip-scale package (8-DSBGA, also designated 8-WFBGA), this part has no leads — the solder balls are the only connection. The 0.50 mm ball pitch demands a solder-mask-defined pad with a 0.30 mm opening and a 0.35 mm copper pad. Rework requires a hot-air station with a fine nozzle; hand-soldering is not practical. Texas Instruments has designated the LM3500TL-16/NOPB as obsolete. No stock-holding or lead-time number is offered here — the quote reflects the real-time market.","metaTitle":"LM3500TL-16/NOPB DC DC Regulator, 16V Boost, 1MHz, Obsolete","metaDescription":"Texas Instruments LM3500TL-16/NOPB is a 1MHz step-up boost regulator with 16V output, 400mA switch, in 8-DSBGA.","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":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Up (Boost)","Frequency":"1MHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"8-WFBGA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Output":"16V","Number of Outputs":"1","Internal Switch(s)":"Yes","Base Product Number":"LM3500","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"7V","Voltage - Supply (Min)":"2.7V","Supplier Device Package":"8-DSBGA","Current - Output / Channel":"400mA (Switch)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$94.8000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6463f7749d559d58941f17865ebf1ac9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3500TL-16%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LM3500TL-16/NOPB obsolete?","answer":"Yes, Texas Instruments lists the LM3500TL-16/NOPB as obsolete.
