Claim 5:
6. The DC-DC converter according to claim 1, wherein the charge-pump circuit unit includes a first charge-pump circuit configured to apply a first output voltage to the first drive unit, a second charge-pump circuit configured to apply a second output voltage to the second drive unit, and an operation control unit configured to control an operation of the first charge-pump circuit and an operation of the second charge-pump circuit, and
the operation control unit is configured to determine a timing at which the first charge-pump circuit is to apply the first output voltage and a timing at which the second charge-pump circuit is to apply the second output voltage, based on the first voltage, the second voltage, and the state of the first conversion operation or the second conversion operation.
