The control circuit is configured for receiving a startup signal during turning on the motherboard. The startup signal is configured to turn off the control circuit to delay a first voltage signal received by the first power receiving terminal for a period of time before outputting a new voltage signal. The switch circuit is configured for being turned off under the control of the new voltage signal. The power conversion circuit is configured for converting a second voltage signal into a supply voltage in response to the switch circuit being turned off, to provide the supply voltage to the motherboard component.

摘要： A voltage providing circuit for a central processing unit (CPU) includes a power supply, three voltage regulation modules, and a pulse width modulation (PWM) controller. The power supply provides three voltages respectively to the three voltage regulation modules. The PWM controller outputs three signals to the three voltage regulation modules. The three voltage regulation modules regulate the voltages from the power supply according to the signals from the PWM controller, and output a regulated voltage to the CPU. The voltage providing circuit also includes three resettable fuses, which are respectively connected between the three voltage regulation modules and the power supply. The resettable fuses automatically shut off the voltage providing circuit when a current is overloading the circuit and turn on the voltage providing circuit when the current is normal.
