Abstract
Controllers and methods for controlling power supplies are disclosed herein. An example of a controller includes comparison circuitry operable to compare a switching frequency of the controller to a predetermined switching frequency. Voltage measuring circuitry is operable to measure the output voltage of the power supply. Circuitry is operable to disable at least one component in the power supply in response to the switching frequency being less than the predetermined switching frequency and the output voltage being greater than a predetermined output voltage.
