Overview
The PCA9633DP2,118, produced by NXP USA Inc., is an I²C-bus controlled 4-bit LED driver optimized for Red/Green/Blue/Amber (RGBA) color mixing applications. This device is part of the Fast-mode Plus (Fm+) family, offering higher frequency and more densely populated bus operation. Each LED output has its own 8-bit resolution (256 steps) fixed frequency Individual PWM controller, allowing for precise brightness control from 0% to 99.6% duty cycle.
