Abstract:
A switching power supply apparatus includes a PFM control circuit that outputs a clock signal Set such that a switching frequency of a switching element varies in accordance with a load state. The clock signal Set determines a turn-on timing of the switching element. A reference value of a current flowing through the switching element determines a turn-off timing of the switching element. A modulation signal is applied to the turn-off timing of the switching element to modulate one of a peak value of a drain current flowing through the switching element and an on-time of the switching element. Input control is performed separately on the clock signal Set and the modulation signal. Accordingly, even when the clock signal Set and the modulation signal contribute to each other to offset each other, modulation effects are not cancelled.

Claim (Index 5):
The switching power supply apparatus of  claim 1 , wherein when a consumption current of the load is equal to or higher than a predetermined value, the switching power supply apparatus operates under PWM control or quasi-resonant control, and when the consumption current of the load is less than the predetermined value, the switching power supply apparatus operates at the oscillation frequency in accordance with the feedback signal.
