Abstract
A gate of the first p-type MOS transistor and the first and second control circuits are electrically coupled to a first node. The first control circuit lowers a voltage or the first node between a first time and a second time at which the first p-type MOS transistor is off. The second control circuit lowers the voltage of the first node between a third time and a fourth time at which the first p-type MOS transistor is on. The second time is later than the first time. The fourth time is later than the second and third times. The first p-type MOS transistor is turned on during a first period. A voltage decrease amount of the first node per unit time in the first control circuit is greater than that in the second control circuit.
