Zusammenfassung:	A controller is configured to perform self-calibration to maintain approximately a desired switching frequency of a power converter. The self-calibration performed by the controller at least partially mitigates detrimental effects associated with variation in an actual switching frequency of the power converter from a designed switching frequency. The controller maintains approximately the desired switching frequency, in one example, in view of a delay inherent in the control by the controller of the power converter.
