IS31FL3191 - Lumissil

IS31FL3191 1-CHANNEL FUN LED DRIVER

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.
