  • Switching power circuit and power supply method
    Publication number: 20100141226
    Abstract: A switching power circuit is provided with a power bypass circuit. The bypass circuit supplies a power supply voltage of an input terminal by bypassing a FET and a ?-filter during a period after supply of the power supply voltage is started until the power supply voltage reaches a predetermined threshold level corresponding to a reference voltage. Even if start of the switching operation of the FET is delayed because of the operation of a soft start circuit, the power supply voltage supplied to a load through the switching power circuit is raised at earlier time.
