PCA9685 LED Driver IC

the pca9685 ic is a 16-channel i2c controller used for controlling red, green, blue, and orange spectrum colors in backlight applications. each output has a 12-bit resolution, and its frequency is adjustable in the range of 24 hz to 1526 hz as a pwm wave from 0 to 100 percent, allowing each led to determine its color.

application of the LED module driver IC:

1. rgba and rgb led drivers
2. led display screens
3. lcd backlight
4. keypad backlight in portable electronic devices
