Abstract
Power conversion efficiency using variable switching frequency. At least some of the example embodiments are power circuit controllers including a voltage sense input and a control signal output. The power circuit controller varies an output frequency of the control signal output between a first frequency and a second frequency based on a source voltage supplied to the power controller. Both the first frequency and the second frequency are non-zero.
