1-CHANNEL FUN LED DRIVER
October 2013
GENERAL DESCRIPTION
IS31FL3191 is a 1-channel fun LED driver which has
One Shot Programming mode and PWM Control mode
for LED 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.
IS31FL3191 is available in UTQFN-9 (1.5mm ×
1.5mm). It operates from 2.7V to 5.5V over the
temperature range of -40°C to +85°C.
FEATURES
 Independently controlled automatic and
semiautomatic
