The PCA9634 is an I2C-bus controlled 8-bit LED driver optimized for
Red/Green/Blue/Amber (RGBA) color mixing applications. 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 % to allow the 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 %
that is used to either dim or blink all LEDs with the same value.
