摘要： A power supply control apparatus, in which a high voltage generated by a switching transistor is prevented from being deviated from a nominal value, includes an arithmetic operator for controlling a duty ratio of switching operation of the switching transistor in response to a feedback value. The arithmetic operator includes a comparator for comparing a reference value with a digitized monitor voltage corresponding to the high voltage, and an adder for adding a minimum unit to the feedback value when the digitized monitor voltage is smaller than the reference value and for subtracting the minimum unit to the feedback value when the digitized monitor voltage is larger than the reference value. The result of addition from the adder is used for controlling the duty ratio of switching operation of the switching transistor.
