Abstract
A DC-DC converter is provided with a control circuitwhich comprises a drive signal generatorfor producing on-off signals to a control terminal of a MOS-FETin synchronization with pulse signals Vfrom an oscillator; an intermittent controllerfor producing a control signal Vto drive signal generatorin response to the level of detection signal from an output voltage detectorto convert MOS-FETto the intermittent operation during the light load period; and a power control circuitfor ceasing power supply Vto oscillatorin response to control signal Vfrom intermittent controllerto stop production of pulse signal Vfrom oscillatorfor the cessation term of MOS-FETduring the intermittent operation.
