Abstract
In an example, a device for operating a switching converter is configured to receive a composite command duty cycle value. The device is further configured to generate an effective duty cycle value based on a voltage at a switching node. The device is further configured to generate a duty cycle mismatch value using the composite command duty cycle value and the effective duty cycle value so as to generate a plurality of duty cycle mismatch values. Each duty cycle mismatch value of the plurality of duty cycle mismatch values corresponds to a candidate natural frequency value of the converter. The device is further configured to output a candidate natural frequency value of the converter that corresponds to a maximum duty cycle mismatch of the plurality of duty cycle mismatch values.
