摘要： A control circuit for controlling a power supply including a first switch and a second switch coupled in series between a first potential and a second potential. The control circuit includes a detection circuit that detects a magnitude relation of a voltage value at a node between the first and second switches and a reference value during a period in which the first switch and the second switch are inactivated. The detection circuit generates a control signal corresponding to the magnitude relation. A regulation circuit regulates a switching timing of the second switch in response to the control signal to decrease a difference between the voltage value at the node and the reference value.

摘要： A control circuit arranged in a power supply including first and second switches to control an output voltage of the power supply. The control circuit includes a first control circuit that switches the first and second switches in a complementary manner in accordance with a comparison result of a first reference voltage and a feedback voltage corresponding to the output voltage of the power supply. A first comparison circuit compares the output voltage or feedback voltage with a second reference value.
