PCA9530 General Description

The PCA9530 is a 2-bit I2C-bus and SMBus I/O expander optimized for dimming LEDs in 256 discrete steps for Red/Green/Blue (RGB) color mixing and backlight applications. The PCA9530 contains an internal oscillator with two user programmable blink rates and duty cycles coupled to the output PWM. The L.
