The LP5018 is an 18-channel constant-current sink LED driver featuring integrated color mixing and brightness control. It includes a 12-bit, 29-kHz PWM generator for each channel to enable smooth dimming and eliminate audible noise. The device supports an ultra-low quiescent current with a power-saving mode that reduces consumption to 10µA when LEDs are inactive. It is designed for human-machine interaction applications such as smart homes, providing features like 3-phase PWM shifting to reduce input power budget and logarithmic or linear scale brightness control.
