Product Introduction

Overview

The PCA9635PW/S911,118, produced by NXP USA Inc., is a 16-bit I²C-bus controlled LED driver optimized for Red/Green/Blue/Amber (RGBA) color mixing applications. This device is designed to provide precise control over LED brightness and color, making it ideal for various lighting and display applications. Each LED output has its own 8-bit resolution (256 steps) fixed frequency individual PWM controller, allowing for adjustable brightness from 0% to 99.6%. Additionally, a group PWM controller enables dimming or blinking of all LEDs with a common value.
