IS31FL3242 - Lumissil

IS31FL3242 4-RGB/12-CH LED DRIVER

The IS31FL3242 is a 12 LED current sink LED driver programmed via 1MHz I2C compatible interface. Each LED can be dimmed individually with 12-bit PWM data and each current sink has 8-bit DC scaling (Color Calibration) data which allowing 4096 steps of linear PWM dimming and 256 steps of DC current adjustable level. Additionally each LED open and short state c.
