Abstract
A power supply apparatus and a driving method thereof are disclosed. The power supply apparatus includes a first converter and a second converter. The first converter is operated to acquire a first gain when an input voltage is included in a first range or a second range that is lower than a first range and outputs a first output voltage and a second output voltage by converting the input voltage. In addition, the second converter is operated when the input voltage is included in the first range and outputs a third output voltage by converting the second output voltage.
