IS31FL3252 - Lumissil

IS31FL3252 4-RGB/12-CH LED DRIVER

The IS31FL3252 is a 12 LED current sinks LED driver programmed via 1MHz I2C compatible interface. Each LED can be dimmed individually with 16-bit PWM data and each color current sinks has 8-bit group DC scaling (Color Calibration) data which allowing 65536 steps of linear PWM dimming for each channel and 256 steps of DC current adjustable level for each colo.
