Abstract:
1. A power control circuit for a power supply, comprising: a clock generator for providing a clock signal; a phase controller for detecting a phase of a group reference signal and a phase of a burst initialization signal to generate a burst signal, so as to cause a phase of the burst signal to occur no earlier than the phase of the group reference signal, wherein the burst signal is capable of switching the power supply between a switching state and a non-switching state; and a power stabilizer for substantially keeping an outputted power of the power supply constant after the power supply is switched from the non-switching state to the switching state; wherein the group reference signal is generated according to the clock signal and has a frequency lower than a frequency of the clock signal; and wherein the burst initialization signal is controlled by an output voltage of the power supply.
