Abstract
A multi-channel power supply system includes a power supply circuit configured to generate a drive signal for powering a plurality of color channels based on an input power signal, a channel controller configured to generate a first pulse width modulated (PWM) signal for controlling an output light intensity of a first color channel of the plurality of color channels, a filter circuit configured to generate a first pseudo-sawtooth signal based on the first PWM signal, and a first current control circuit coupled to a first color channel of the plurality of color channels and configured to adjust a first channel current of the first color channel based on the drive signal and the first pseudo-sawtooth signal.
