IS31FL3193
3-CHANNEL FUN LED DRIVER
GENERAL DESCRIPTION
IS31FL3193 is a 3-channel fun LED driver which
features two-dimensional auto breathing mode. It has
One Shot Programming mode and PWM Control mode
for RGB lighting effects. The maximum output current
can be adjusted in 5 levels (5mA~42mA).
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.
IS31FL3193 is available in DFN-10 (3mm × 3mm). It
operates from 2.7V to 5.5V over the temperature range
of -40°C to +85°C.
