Abstract
A switching delay controller is configured to control a switching delay between the switching of first and second switching elements in a switched mode power supply. The switched mode power supply generates a feedback signal indicative of a difference between an output of the switched mode power supply and a reference for the output, and switches the first and second switching elements to convert an input voltage into an output voltage based on the feedback signal. The switching delay controller includes a switching delay calculator operable to cause a change of the switching delay for at least one switching cycle of the switched mode power supply, and a feedback signal monitor operable to monitor the feedback signal and determine a change in the feedback signal in response to the change of the switching delay by the switching delay calculator.
