Abstract
A power converter includes a single magnetic element in communication with a plurality of output channels. Each output channel includes one or more light-emitting diodes (LEDs) that may output a desired light output. Desired amounts of current may be discharged from the single magnetic element through the LEDs to generate the desired light output. The current may be drawn through the LEDs by switching 'on' and 'off' switches connected to the LEDs. A controller in communication with the power converter may generate switching signals to turn “on” and “off” the switches to draw the desired amounts of current. The controller may measure the current and determine whether to adjust the switching signals if the measured current draw is not the desired current draw in order to generate the desired light output from the LEDs.
