Overview
PCA9622 16-bit Fm+ I2C-bus 100 mA 40 V LED driver Rev.
5 — 2 June 2014 Product data sheet 1.
General description The PCA9622 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 adju...
