ABSTRACT:
An output terminal of a first boost circuit is connected to a second boost circuit. After the second boost circuit is started up, a boost clock frequency of the second boost circuit is reduced. A time required to start up the second boost circuit is reduced, and in addition, a current supply capability of the first boost circuit is increased after the second boost circuit is started up. When the second boost circuit is driven, output voltages of the first and second boost circuits are stably supplied without instantaneously changing the output voltage of the first boost circuit.
