Claim 0:
1. A DC-DC converter that outputs a DC output voltage between a first output terminal and a second output terminal by performing power conversion on a DC input voltage, the DC-DC converter comprising:
a conversion circuit that outputs an intermediate voltage which is obtained by performing power conversion on the input voltage, between a first intermediate terminal and a second intermediate terminal;
a first coil provided between the first intermediate terminal and the first output terminal;
a second coil; and
a diode provided in series with the second coil, wherein
the DC output voltage is applied to the second coil and the diode provided in series, with a polarity in a direction in which a reverse bias is applied to the diode, and
the first coil and the second coil are magnetically coupled such that a current is made flow through the second coil in a forward direction of the diode by mutual induction as a current flowing through the first coil in a direction from the first intermediate terminal to the first output terminal increases.
