IS31FL3189
AUDIO MODULATED LED DRIVER
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.
In One Shot Programming mode, the timing
characteristics for output current - current ramping up,
holding, ramping down and off time, can be adjusted
individually so that each output can independently
maintain a pre-established pattern without requiring
any additional interface activity, thus saving valuable
system resources.
In Interface Intensity Control mode, the PWM duty
cycle of each output can be independently
programmed and controlled in 256 steps to simplify
color mixing.
