The PCA9625 is an I2C-bus controlled 16-bit LED driver optimized for voltage switch
dimming and blinking 100 mA Red/Green/Blue/Amber (RGBA) LEDs. 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.
