TYPICAL APPLICATION
The CAT3626 is ideal for driving RGB (red green blue)
LEDs with common anode configuration. The
individual LED currents associated with the red, green
and blue LEDs are programmable independently
through the I²C interface, allowing to generate an
accurate color mixing. Dimming while maintaining the
same color can be done by reprogramming the RegEn
register on and off with the appropriate duty cycle
(PWM mode).
