Abstract
The disclosure provides a power supply circuit including a pulse width modulator (PWM), a first voltage conversion unit, a second voltage conversion unit, a conversion chip, and a delay unit. The first voltage conversion unit converts a voltage of a power supply to a first voltage according to pulse signals output by the PWM. The second voltage conversion unit converts the voltage of the power supply to a second voltage according to the pulse signals. The conversion chip converts the first voltage to a third voltage, converts the second voltage to a fourth voltage, and outputs a power-good signal to a south bridge chipset through the delay unit. The disclosure also provides a notebook computer including the power supply circuit.
