Abstract
In one embodiment of the present invention, an output control device is disclosed capable of reducing a chip size and realizing a low cost. An output control device includes a switching transistor controlling an output voltage by having an on/off time ratio controlled and a control IC controlling the on/off time ratio of the switching transistor on the basis of the output voltage controlled by the switching transistor. The switching transistor is made of a lateral power MOSFET.
