Claim 8:
9. 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
an external DC voltage generated by a DC voltage generation unit is applied to the second coil and the diode provided in series,
the external DC voltage generated by the DC voltage generation unit 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.
