    Abstract: An overload protection saving circuit provided by the present invention has an input power circuit, an output power circuit, a control circuit, an overload timing circuit, and a saving circuit. The output power circuit couples to the input power circuit. The control circuit receives a feedback signal of the output power circuit in order to control the input power circuit. The overload timing circuit receives the feedback signal of the output power circuit in order to transmit an overload signal to the control circuit while the time of an overload is over a predetermining time. The saving circuit receives the feedback signal of the output power circuit in order to transmit a saving signal to the overload timing circuit while in a lightload or a noload, so that the overload timing circuit is disabled.
