Abstract:
1. A frequency-hopping control method to be performed by a frequency-hopping control module that is suitable for use with a voltage converting circuit and that generates a driving signal for driving the voltage converting circuit when the voltage converting circuit operates in a frequency-hopping mode such that the voltage converting circuit generates an output voltage, comprising the steps of: (A) generating a periodic pulse signal; (B) generating a control signal according to a regulating signal that is inversely proportional to the output voltage of the voltage converting circuit, wherein the control signal is cyclical and each cycle of the control signal includes an off-time and an on-time, the on-time having a substantially fixed duration, the off-time having a variable duration that has an inverse relation to magnitude of the regulating signal; and (C) generating the driving signal according to the control signal and the pulse signal for driving the voltage converting circuit.
