Abstract:
A switching power supply apparatus includes a switching device and a switching power supply control circuit for converting an AC source voltage to a DC voltage. A comparison circuit in the switching power supply control circuit produces an H-level output signal when its non-inverted input voltage exceeds a voltage value during each off-state period of the switching device. A delay circuit outputs a pulse signal after a predetermined delay time from detecting the H-level signal. This pulse signal indicates detection of a bottom point of drain voltage of the switching device. Since the output of the delay circuit is directly connected to the set input terminal S of a flip-flop, the switching device is surely turned on, without bottom skip, upon detection of the bottom point of its drain voltage.

Claim (Index 3):
The switching power supply control circuit according to  claim 1 , wherein:\n the first converter is implemented in a first semiconductor integrated circuit; the second converter is implemented in a second semiconductor integrated circuit that is separate from the first semiconductor integrated circuit; and the first semiconductor integrated circuit and the second semiconductor integrated circuit are mounted together in a single package.
