3 Description

The TLC59116 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%.
