Discussed is a protection circuit for a direct current-direct current (DC-DC) converter, the protection circuit including a buck switch connected between a voltage input terminal and a first node, the buck switch being controlled by a switching cycle and a duty cycle of a switching signal, a buck inductor connected between the first node and a voltage output terminal, a buck capacitor connected between the voltage output terminal and a ground, and a buck diode connected between a second node and the ground. The protection circuit is connected to the first node, the second node and the ground. When the buck switch is switched between an On state and an OFF state according to the switching signal, the protection circuit is configured to supply a protection voltage between the first node and the ground so that voltage stress of the buck switch is smaller than an input voltage supplied between the voltage input terminal and the ground.
