Provided is an electronic equipment including: a boost DC-DC converter and
an electric power storage device, in which the electric power storage
device is charged with a electric power outputted the DC-DC converter
with efficiency, and in which stored electric power of the electric power
storage device is not wastefully consumed even when supply of the
electric power is stopped. The electronic equipment including the power
supply, the boost DC-DC converter, a rectifier rectifying a pulse-like
boosted electric power outputted the DC-DC converter to a second boosted
electric power, and the electric power storage device for charging a
first boosted electric power from the boost DC-DC converter, wherein an
operation of the boost DC-DC converter is maintained by the second
boosted electric power.
