This invention synchronizes the control signals generated by the out-of-range detection circuits with a predefined event. In one aspect, the invention relates to a method of controlling a switching regulator to regulate an output voltage. The method includes receiving a first enable signal and a second enable signal, comparing a feedback voltage representative of the output voltage to a first reference voltage and generating a first limit signal in response thereto and generating, in response to the first enable signal, a close switch command if the first limit signal indicates that the feedback voltage is less than the first reference voltage. The method further includes comparing the feedback voltage to a second reference voltage and generating a second limit signal in response thereto and generating, in response to the second enable signal, an open switch command if the second limit signal indicates that the feedback voltage is greater than the second reference voltage.
