The part supports both analog and PWM dimming, so the designer can choose continuous current adjustment or a digital pulse-width interface depending on the host controller. ## Industrial temperature range — where this boost regulator fits The 10-bump DSBGA package (1.9 mm x 2.07 mm) demands careful board-level assembly — the small footprint and fine pitch mean a controlled reflow profile and X-ray inspection for solder-joint integrity are recommended. This part carries an official Obsolete status. Any stock available in the independent distribution channel is new-old-stock or surplus material — date-code and quantity verification are essential for a production run. ## Sourcing reality — how to fill this line Because this part is obsolete, it is not available through the manufacturer's standard distribution.","metaTitle":"LM3503ITL-16/NOPB LED Driver, Boost Regulator, 16V Output","metaDescription":"Texas Instruments LM3503ITL-16/NOPB DC DC boost regulator for LED backlight. 16V output, 2 channels, 400mA switch, 1MHz, industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"DC DC Regulator","Series":"-","Dimming":"Analog, PWM","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Up (Boost)","Frequency":"1MHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"10-WFBGA, DSBGA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Output":"16V","Number of Outputs":"2","Internal Switch(s)":"Yes","Base Product Number":"LM3503","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"5.5V","Voltage - Supply (Min)":"2.5V","Supplier Device Package":"10-TµSMD (1.9x2.07)","Current - Output / Channel":"400mA (Switch)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3700","priceTiers":[{"qty":219,"price":"$1.37000","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3503ITL-16%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LM3503ITL-16/NOPB available via RFQ confirmation?","answer":"This obsolete part is sourced through independent distribution.
