General Description

The IS31FL3189 is an LED driver with an audio synchronization mode that virtually eliminates the need of real time software processing for LED lighting effects.

The OUT0~9 can be operated at 4 basic modes: Audio synchronization mode, top-down scan mode, constant current mode, combination of audio synchronization and top-down scan mode.

Each of the OUT0~2, OUT7~9 is a constant current sink pulse width modulated in 256 steps, featuring One Shot Programming mode and Interface Intensity Control mode for RGB lighting effects.
