Systems and Methods of Driving Multiple Outputs

Systems and methods of driving multiple outputs are provided in which a single inductor (105) may be used to drive multiple output such as independent strings of LEDs or white LEDs (WLEDs)(215, 220). In an example embodiment, a boost DC to DC converter (100) may be used with a single inductor (105) to drive multiple outputs. In an example embodiment, the error voltage of each of the multiple outputs is sampled during each cycle of the DC to DC converter (100) and the largest error voltage is determined for that cycle. Power from the DC to DC converter (100) is then supplied to that output during that cycle.
