ABSTRACT:
A switching power supply includes an active device for pulling out a part of a control signal from a control terminal of the switching device in an RCC, and a control signal generation circuit that applies adjustment voltage as ON/OFF time control voltage to a control terminal of the active device. The active device pulls out the control signal so as to decrease or increase an OFF time of the switching device while fixing the ON time of the switching device when the adjustment voltage is decreased or increased in the active region of the active device, respectively. An element of a timing circuit in the RCC pulls out the control signal so as to increase or decrease an ON time of the switching device while fixing the OFF time of the switching device when the adjustment voltage is decreased or increased in the cut-off region of the active device, respectively.
