IS31FL3199
9-CHANNEL LIGHT EFFECT LED DRIVER
GENERAL DESCRIPTION
IS31FL3199 is a 9-channel light effect LED driver
which features two-dimensional auto breathing mode
and an audio modulated display mode. It has One Shot
Programming mode and PWM Control mode for RGB
lighting effects. The maximum output current can be
adjusted in 8 levels (5mA~40mA).
In PWM Control mode, the PWM duty cycle of each
output can be independently programmed and
controlled in 256 steps to simplify color mixing. In One
Shot Programming mode, the timing characteristics for
output current - current rising, holding, falling and off
time, can be adjusted individually so that each output
can independently maintain a pre-established pattern
achieving mixing color breathing or a single color
breathing without requiring any additional interface
activity, thus saving valuable system resources.
The IS31FL3199 includes an audio modulated display
mode, wherein the brightness of LED can be
modulated by audio signal. There is a cascade pin for
the synchronization of two chips.
IS31FL3199 is available in QFN-20 (3mm × 3mm). It
operates from 2.7V to 5.5V over the temperature range
of -40°C to +85°C.
