Abstract
A voltage control circuit includes a voltage step-up device that steps up an applied voltage to a stepped-up voltage, an electronic device to which the stepped-up voltage is applied, a current monitor that monitors a supplied current that is supplied to the electronic device, based on the stepped-up voltage, a step-up controller that controls the stepped-up voltage to be a predetermined target voltage, based on the supplied current, and a warning provider that provides a warning when the current monitor can not monitor the supplied current.
Claims10
A voltage control circuit comprising;
- a voltage step-up device that steps up an applied voltage to a stepped-up voltage;
- an electronic device to which said stepped-up voltage is applied;
- a current monitor that monitors a supplied current that is supplied to said electronic device, based on said stepped-up voltage;
- a step-up controller that controls said stepped-up voltage to be a predetermined target voltage, based on said supplied current;
- and
- a warning provider that provides a warning when said current monitor can not monitor said supplied current.
