Claim 0:
1. A multi-channel power supply system comprising:
a power supply circuit configured to generate a drive signal at a secondary winding of the power supply circuit for powering a plurality of color channels based on an input power signal;
a plurality of rectifiers coupled between the power supply circuit and the plurality of color channels, each rectifier of the plurality of rectifiers being directly coupled to a same output of the secondary winding and coupled to a different one of the plurality of color channels;
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 a first reference signal; and
a channel controller configured to control the first current control circuit by generating the first reference signal based on a color temperature according to a black body curve and further based on a dimmer setting from a dimming controller.
