摘要
The switching power supply device is provided with a high-withstand voltage first transistor, a first electrode of which being connected to a first node; a low-withstand voltage second transistor, a first electrode of which being connected to a second electrode of the first transistor, and a second electrode of which being connected to a second node; and a drive circuit. Each of the first and second transistors has a parasitic diode connected in the forward direction between the second and first electrodes. The drive circuit, in a case where electrical current is to flow from the first node to the second node, turns on the first and second transistors, and, in a case where electrical current is to flow from the second node to the first node, turns on the first transistor, and turns off the second transistor.
