Abstract:
A switching element with a small current capacity is provided to be able to be used in a DC-DC converter. The DC-DC converter includes a switching circuit in which a first switching element, a second switching element, a third switching element, and a fourth switching element are connected in series, a flying capacitor that is connected between a connection portion between the first switching element and the second switching element and a connection portion between the third switching element and the fourth switching element, a reactor that is connected between a connection portion between the second switching element and the third switching element and a positive electrode of an input unit, and a control circuit that turns on/off the switching element, in which the control circuit turns on/off the switching elements so that a peak value in a reactor current becomes equal to or smaller than a predetermined value.

Claim (Index 1):
A DC-DC converter that boosts a DC input voltage to obtain a DC output voltage, the DC-DC converter comprising:\n a switching circuit of which both terminals are connected to an output unit that outputs the DC output voltage and in which four switching elements are connected in series in an order of a first switching element, a second switching element, a third switching element, and a fourth switching element; a flying capacitor that is connected between a connection portion between the first switching element and the second switching element and a connection portion between the third switching element and the fourth switching element; a reactor that is connected between a connection portion between the second switching element and the third switching element and a positive electrode of an input unit to which the DC input voltage is input; and a control circuit that determines a period of a first mode according to a predetermined timing and current peak value, and turns on or turns off each switching element in the switching circuit at the predetermined timing, wherein the control circuit turns on or turns off each of the switching elements based on the period of the first mode so that a maximum value in a reactor current flowing through the reactor becomes equal to or smaller than a predetermined value.
