Abstract
A DC-DC converter having a switching element and a synchronous rectifier, the switching element undergoing a switching operation, the converter performing a voltage conversion of an input voltage to provide a converted output voltage at an output/input conversion ratio that is determined by the switching operation of said switching element, the converter delivering the converted output voltage to a load, said DC-DC converter further comprising: a reverse current detector for detecting a reverse current which flows from an output of the converter to an input of the converter, and a reverse current suppressor, the reverse current suppressor controlling the switching operation of said switching element so as to increase the output/input conversion ratio when a reverse current is detected by the reverse current detector, thereby suppressing the reverse current.
