IS31FL3299 Overview
The IS31FL3299 is a 9 LED current sink LED driver with 1MHz I2C patible programming interface. Each LED can be dimmed individually with 12-bit PWM data and color calibrated with 8-bit DC scaling data, which provides 4096 steps of linear PWM dimming and 256 steps of DC current adjustable levels. All channels output current can be further globally adjusted in 64 steps.
