Its two independent outputs allow separate control of two LED strings, each regulated to a 35 V ceiling. PWM dimming on each channel gives the system controller fine brightness control without shifting the LED colour point. No direct replacement or successor part is published on the TI website for this exact order code. The base product number LM3502 has no active follow-on in the same pinout. The ROHS3 compliance is intact — no lead-free transition concern for existing designs.","metaTitle":"LM3502SQ-35/NOPB — TI DC-DC Boost Regulator, 35V, Obsolete","metaDescription":"Texas Instruments LM3502SQ-35/NOPB DC-DC boost regulator, 35V output, 2 channels, PWM dimming, 1 MHz switching.
