PCA9632 Datasheet 4-bit Fm I2C-bus low power LED driver

Manufacturer: NXP Semiconductors

General Description

The PCA9632 is an I2C-bus controlled 4-bit LED driver optimized for Red/Green/Blue/ Amber (RGBA) color mixing applications.

The PCA9632 is a drop-in upgrade for the PCA9633 with 40× power reduction.

In Individual brightness control mode, each LED output has its own 8-bit resolution (256 steps) fixed frequency Individual PWM controller that operates at 1.5625 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.
