PCA9685 Datasheet (NXP Semiconductors) - 12-bit PWM Fm I2C-bus LED controller

PCA9685, 12-bit PWM Fm I2C-bus LED controller

The PCA9685 is an I2C-bus controlled 16-channel LED controller optimized for Red/Green/Blue/Amber (RGBA) color backlighting applications.

Each LED output has its own 12-bit resolution (4096 steps) fixed frequency individual PWM controller that operates at a programmable frequency from a typical of 2
