Abstract

PURPOSE: To reduce the thermal designing and packaging limitations by securing such a constitution where the control signal received from an overcurrent detection means does not effect a control element at all during a normal power supply action when no overcurrent is detected and the control signal received from an output voltage fluctuation detection means is supplied to the control element via a matching means.
CONSTITUTION: An output voltage fluctuation detection means 101 outputs a control signal in accordance with the fluctuation component of the output voltage. An overcurrent detection means 102 outputs a control signal in accordance with detection of a load current higher than a prescribed level. A matching means 103 performs a matching operation to secure a wired OR between the control signals of both means 101 and 102. A control element 104 is inserted in series between an input DC power supply and a load and the both-end impedance of the element 104 changes in accordance with the control signal received from the means 103. Thus the output voltage is stabilized and an overcurrent is limited. As a result, since the hardware scale is reduced owing to a simple constitution of a single control element the packaging limitation is reduced. Furthermore the thermal designing limitation is also reduced.
