PCA9633 4-bit Fm I2C-bus LED driver

PCA9633 Description

PCA9633 4-bit Fm+ I2C-bus LED driver Rev.6.0 * 19 January 2023 Product data sheet 1 General .
The PCA9633 is an I2C-bus controlled 4-bit LED driver optimized for Red/Green/Blue/ Amber (RGBA) color mixing applications.

PCA9633 Features

* 4 LED drivers. Each output programmable at:
* Off
* On
* Programmable LED brightness
* Programmable group dimming/blinking mixed with individual LED brightness
* 1 MHz Fast-mode Plus I2C-bus interface with 30 mA high drive capability on SDA out

PCA9633 Applications

* 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. A fifth 8-bit resolution (256 steps) Group PWM controller has
