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 3):
The DC-DC converter according to  claim 1 , wherein the first mode in which the first switching element and the second switching element in the switching circuit are turned off and the third switching element and the fourth switching element are turned on, a second mode in which the first switching element and the third switching element are turned off and the second switching element and the fourth switching element are turned on, a third mode in which the second switching element and the fourth switching element are turned off and the first switching element and the third switching element are turned on, and a fourth mode in which the third switching element and the fourth switching element are turned off and the first switching element and the second switching element are turned on,\n wherein the control circuit determines the period of the first mode so that a maximum value of the reactor current in the first mode is smaller than a current according to a current capacity of each of the switching elements in the switching circuit.
