IS31FL3189 AUDIO MODULATED LED DRIVER November 2011 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. The output current is user selectable to be one of 5 levels, 17.5mA, 28.9mA, 38.9mA, 46.7mA or 66.5mA (typical). At 38.9mA the IS31FL3189 outputs require only 0.4V of headroom voltage.
