Overview

NXP PCA9956B 24-channel LED Driver is an I�C-bus controlled constant current driver designed for dimming and blinking 57mA 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 31.25kHz with a duty cycle that is adjustable from 0% to 100% 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 122Hz and an adjustable frequency between 15Hz to once every 16.8 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.
