Abstract: PURPOSE: A method of a DC-DC converter is provided to determine an ultra low load state of a DC-DC converter, thereby effectively preventing over-heating and damage of a switching device in a converter. CONSTITUTION: A DC-DC converter operates(S11). A converter controller receives a converter output terminal voltage and an output current which are detected by a voltage sensor and a current sensor. The voltage sensor and the current sensor are installed in a converter output terminal. The converter controller monitors the operation state of the converter(S12). The output current of the DC-DC converter is maintained under a reference current during a fixed period of time(S13,S14). An ultra low load state is determined(S15). The operation state of the converter is compared with a predetermined PWM off prohibition condition in the ultra low load state(S16,S17). A normal operating mode enters a PWM off mode(S18). A predetermined PWM off mode release condition is determined(S19). The PWM off mode is released(S20).
