Lumissil IS31FL3252/4/8 and IS31FL3018

The IS31FL3252/4/8 and IS31FL3018 are a family of 4/8/6 RGB LED Drivers programmed via a 1MHz I2C compatible interface. Each LED can be dimmed individually with 16-bit PWM data. The output current of each channel can be set up to 27.5mA (max.), all channels are grouped as G group (OUT1, OUT4, OUT7...), R group (OUT2, OUT5, OUT8...), B group (OUT3, OUT6, OUT9...) and each group has 8 bits output current control register which allows fine-tuning of the current for rich global RGB color mixing

Key features
