3 Description

The TLC59116-Q1 is an I2C-Bus controlled 16-

channel LED driver that is optimized for

red/green/blue/amber (RGBA) color mixing and

backlight application. 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%.
