Abstract
A switching power supply comprises one or more power supply stages configured to receive power from an input power source and to generate an output voltage for powering a load by alternately opening and closing a set of switches. An output current sensor is configured to monitor a level of an output current of the switching power supply. The opening and closing of the set of switches is controlled so as to maintain the output voltage at a desired level when the level of the output current is below the threshold and so as to limit the output current when the level of the output current exceeds the threshold.
