Product Summary

The TLC59108IPW 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. The TLC59108IPW is one of the first LED controller devices in a new Fast-mode Plus (Fm+) family. Each LED output of the LC59108IPW 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%.
