Classification: CPC H  G | IPC G  H

Claim 0:
1. A power control device comprising:
an output voltage controller configured to control an output voltage of a power supply circuit based on a feedback voltage obtained by dividing the output voltage;
a first overvoltage protection circuit that includes an output voltage detector configured to detect whether the output voltage has exceeded an output voltage threshold value and a feedback voltage detector configured to detect whether the feedback voltage has fallen to or below a feedback voltage threshold value, and that is configured to continues or stops operation of the output voltage controller based on a first detection output from the output voltage detector and a second detection output from the feedback voltage detector; and
a second overvoltage protection circuit configured to stop operation of the output voltage controller based on the feedback voltage exceeding an overvoltage set value.
