Abstract
A DC-DC converter can include a driving circuit comprising a switch part and a flying capacitor configured to convert an input voltage of an input side into an output voltage of an output side, and a protection circuit configured to be connected to the output side. The protection circuit can be configured to block the fault current flowing to the switch part by lowering the output voltage step by step when a fault occurs.
