ABSTRACT:
A quickly restartable power supply apparatus which can quickly restart with a power-saving integrated circuit in power-saving mode by utilizing the reference output signal of the power control circuit as a restarting control signal thereby rapidly restarting the power supply apparatus in power-saving mode with lower circuitry complexity and cost and good reliability. Further, the quickly restartable power supply apparatus can also decrease the power dissipated by the starting resistor by using the reference voltage signal to control the switch control circuit and the second switching means such that after the power supply control circuit is activated, the current in the starting resistor is cut off and no power is dissipated by the starting resistor.
