摘要： The present invention relates to a converter and a driving method thereof. The converter includes a switch controller that controls switching operation of a master switch and a slave switch. The switch controller detects a center point of one switching operation period of the master switch by using an internal triangular wave having a period that is the same as that of the one switching operation period, and starts the switching operation of the slave switch at the detected point. The internal triangular wave signal has a waveform that varies within one period, and detects a crossing point of an average value of the internal triangular wave and the internal triangular wave as a center point of one switching operation period of the master switch.

摘要： A converter and a driving method thereof are provided. The converter can determine the output short state of the converter after the soft start is finished by using a detection signal that corresponds to an input signal while a switched is turned on and that corresponds to an output signal while the switch is turned off, so as to convert the input signal into the output signal according to a switching operation of the switch. The converter can determine the overload state of the converter by using a feedback voltage corresponding to the output signal, and terminate the switching operation when the converter is in an output short state or overload state.
