Claim 16:
17. A multi-channel power supply system comprising:
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;
a first current control circuit coupled to the 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;
a second current control circuit coupled to a second color channel of the plurality of color channels and configured to adjust a second channel current of the second color channel based on the drive signal and a second pseudo-sawtooth signal; and
a third current control circuit coupled to a third color channel of the plurality of color channels and configured to adjust a third channel current of the third color channel based on the drive signal and a third pseudo-sawtooth signal.
