The LM3535 is a highly integrated LED driver capable of driving 8 LEDs in parallel. It features three independently controlled groups (Group A for up to 6 main display LEDs, Group B, and Group C for secondary displays/indicators). The device includes a charge pump operating in 1x or 3/2x gain modes for efficiency up to 90%, and supports 128 exponential dimming steps with a 600:1 ratio. It integrates multi-zone ambient light sensing (ALS) and a PWM input for dynamic backlight control content-based adjustment.
