Abstract
A method for stabling a voltage, a pulse frequency modulating circuit and a power supply using the same are provided. The method includes the following steps. First, a comparing signal is provided. Then, set the comparing signal to be a first logic state when the voltage to be stabilized is lower than a preset voltage. Next provide a pulse signal when the comparing signal is set in the first logic state. Afterwards, adjust the enable time of the pulse signal based on the number of times of logic state changing of the comparing signal within a preset period and, adjust the voltage according to the enable time of the pulse signal.
