Zusammenfassung:	A control circuit and a method for a programmable power supply are provided. The control circuit and the method modulate a switching frequency of a switching signal in response to a feedback signal and an output voltage of the programmable power supply. The switching signal is used for switching a transformer and regulating an output of the programmable power supply. The level of the feedback signal is related to the level of an output power of the programmable power supply. The output voltage of the programmable power supply is programmable. Further, the control circuit and the method modulate a maximum switching frequency of the switching signal in response to the output voltage of the programmable power supply for stabilizing the system.
