Claim 4:
5. The drive circuit according to claim 3, wherein
the chopper circuit includes:
a booster circuit; and
a step-down circuit, and

the step-down circuit includes:
an inductor, wherein a first end of the inductor is connected to one of the positive-side terminal or the negative-side terminal;
a step-down-side diode having an output terminal connected to a second end of the inductor;
a step-down-side transistor, wherein
a source of the step-down-side transistor is connected to the second end of the inductor,
a drain of the step-down-side transistor is connected to the node, and
a pulse width modulation signal is input, where voltage is to be stepped-down, to a gate of the step-down-side transistor.
