The PCA9685PW is an I²C-bus controlled 16-channel LED controller optimized for LCD RGBA colour 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 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 specific brightness value. All outputs are set to the same PWM frequency.
● Programmable LED brightness
● Programmable LED turn-on time to help reduce EMI
● 25 MHz typical internal oscillator requires no external components
● Internal power-on reset
● Noise filter on SDA/SCL inputs
● Edge rate control on outputs
● No output glitches on power-up
● Supports hot insertion
● Low standby current
