Beschreibung
Zusammenfassung:	A method for controlling a power converter includes receiving an input signal through an input node and generating an intermediate signal using a capacitor, generating a control signal in response to the input signal and the intermediate signal, coupling or decoupling the input node and the capacitor in response to the control signal, and generating an output signal in response to the intermediate signal. A circuit for controlling a power converter includes an input node receiving an input signal, a first capacitor providing an intermediate signal, a detection circuit generating a control signal in response to the input signal and the intermediate signal, a switching device coupling the input node and the first capacitor in response to the control signal, and a regulator generating an output signal in response to the intermediate signal.
