1. A method of operating a switched mode power supply circuit, the method comprising: determining an error in a control signal for a switched mode power supply circuit; comparing the error to an error threshold value to provide a filtering selection; adapting filtering of the error based on the filtering selection to provide a selected filtering; and filtering the error using the selected filtering, wherein determining an error in a control signal comprises comparing a present value of the control signal to a target value of the control signal, wherein the control signal comprises a duty cycle value of a switching signal provided to the switched mode power supply circuit and the target value comprises a duty cycle target value for the switched mode power supply circuit, wherein the error comprises a duty cycle error value and the error threshold comprises a duty cycle error threshold value; and wherein comparing comprises comparing the duty cycle error value to the duty cycle error threshold value to provide the filtering selection to an overhead regulator configured to provide operational commands to a voltage regulator.
