Abstract

A DC/DC converter and an audio device incorporating the same performs a switching operation of a transistor through a driving control merely by an oscillation circuit under a light load condition other than a switching control circuit which shows a low conversion efficiency under a light load condition, thereby the conversion efficiency therewith under a light load condition is improved.
