Abstract
There is provided a control circuit which controls a DC-DC converter which boosts an output voltage of an input source and outputs the output voltage which has been boosted, in which the DC-DC converter has a boost coil, and a capacitor, and the control circuit includes: an input terminal into which the output voltage is input; a first transistor arranged between the input terminal, and the boost coil and the capacitor; and a switch activation unit which boosts the output voltage, and applies the output voltage, which has been boosted, to a control terminal of the first transistor.
