  • Patent number: 8179106
    Abstract: A synchronous-rectifier type DC-DC converter includes a high-side main switch element, a low-side rectifying switch element, and a control drive circuit. The rectifying switch element includes a rectifying transistor element and a rectifying diode element connected in antiparallel with the rectifying transistor element. The control drive circuit detects an input voltage to the main switch element and determines the input voltage or a rate of increase in the input voltage. When the determined value exceeds a predetermined reference value, a complementary ON/OFF operation of the main switch element and the rectifying transistor element is released, and a state where both the main switch element and the rectifying transistor element are kept OFF for a time period that is longer than a dead-time during the complementary ON/OFF operation is set.
