1. General description
The PCU9656 is a UFm I2C-bus controlled 24-bit LED driver optimized for voltage switch dimming and blinking 100 mA Red/Green/Blue/Amber (RGBA) LEDs. Each LEDn output has its own 8-bit resolution (256 steps) fixed frequency individual PWM controller that operates at 97 kHz (typical) 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 frequency of 190 Hz and an adjustable frequency between 24 Hz to once every 10.73 seconds with a...
