16-channel, 12-bit PWM Fm+ I 2C-bus LED Controller

The PCA9685 is an I2C-bus controlled 16-channel LED controller optimized for LCD Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has its own 12-bit resolution (4096 steps) xed frequency individual PWM Controller that operates at a programmable frequency from a typical of 40 Hz to 1000 Hz with a duty cycle that is adjustable from 0 % to 100 % to allow the LED to be set to a specic brightness value. All outputs are set to the same PWM frequency. By NXP Semiconductors
