Abstract:
A control circuit according to an embodiment of the present invention is configured to control a switching element of a switching power supply. The control circuit includes a comparator having a first input terminal configured to receive an output voltage of the switching power supply. The comparator has a second input terminal that is connectable to a positive terminal of a reference voltage source. The comparator has an output. The output brings the reference voltage to a first voltage while the output signal takes a first voltage level. The output brings the reference voltage to a second voltage while the output signal takes a second voltage level. The constant voltage source has a positive terminal connected to a negative terminal of the reference voltage source and a ground of the comparator.

Claim (Index 1):
A control circuit configured to be connected to a first switching element connected to a first output terminal and a second output terminal, the first output terminal being higher in voltage level than the second output terminal, the control circuit comprising:\n a first reference voltage source having a reference voltage; a first resistor and a second resistor that are connected in series to each other to voltage-divide an output voltage between the first output terminal and the second output terminal; a first comparator having a first input terminal, a second input terminal, and a first output terminal, the first input terminal being connected between the first resistor and the second resistor and configured to receive the output voltage voltage-divided, and the second input terminal being connected to the first reference voltage source and configured to receive the reference voltage; a capacitor connected in parallel to the first resistor, the capacitor and the first resistor being connected in parallel between the first output terminal and the second resistor; and a controller configured to be connected between the first output terminal of the first comparator and the first switching element, the controller being configured to control the first switching element based on an output of the first comparator, wherein the reference voltage has a first voltage value in a case that the output of the first comparator is at a first voltage level, the reference voltage has a second voltage value in a case that the output of the first comparator is at a second voltage level different from the first voltage level, and the second voltage value is different from the first voltage value.
