Abstract
In accordance with an embodiment, a controller for a switched mode power supply includes an average current comparator that determines whether an average current within the switched mode power supply is below a current threshold, and a switch signal generation circuit coupled to the average current comparator having switch signal outputs configured to be coupled to a switching circuit of the switched mode power supply. The switch signal generation circuit produces a first switching pattern in a first mode of operation and produces a second switching pattern a second mode of operation. When the average current comparator determines that the average current is below the current threshold, the switch signal generation circuit is operated in a first mode, and when the average current comparator determines that the average current is not below the current threshold, the switch signal generation circuit is operated in a second mode.
