8-BIT Fm+ I2C-BUS CONSTANT-CURRENT LED SINK DRIVER

The TLC59108 is an I2C bus controlled 8-bit LED Driver that is optimized for red/green/blue/amber (RGBA) color mixing and backlight application for amusement products. Each LED output has its own 8-bit resolution (256 steps) fixed-frequency individual PWM Controller that operates at 97 kHz, with a duty cycle that is adjustable from 0% to 99.6%. The individual PWM Controller allows each LED to be set to a specific brightness value. An additional 8-bit resolution (256 steps) group PWM Controller has both a fixed frequency of 190 Hz and an adjustable frequency between 24 Hz to once every 10.73 seconds, with a duty cycle that is adjustable from 0% to 99.6%. The group PWM Controller dims or blinks all LEDs with the same value. By Texas Instruments
