1-CHANNEL FUN LED DRIVER July 2021 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 -...
