Abstract: A frequency-hopping control method is performed by a frequency-hopping control module that generates a driving signal for driving a voltage converting circuit to generate an output voltage. The method includes, generating a control signal according to a regulating signal inversely proportional to the output voltage of the voltage converting circuit. The control signal is cyclical, and each cycle of which includes an off-time having a variable duration with an inverse relation to magnitude of the regulating signal, and an on-time having a substantially fixed duration. The driving signal is generated according to the control signal and a periodic pulse signal. Therefore, the output voltage can be stabilized, and the voltage converting circuit can perform voltage conversion with reduced power loss and improved voltage conversion efficiency.
