Abstract
A discharge circuit for a power supply unit includes a pulse width modulator (PWM) chip, a first and second electronic switch, and a resistor. The first electronic switch receives a power good signal from the power supply unit. When a system power terminal outputs a voltage later than a stand-by power terminal, a voltage creep outputted by the PWM chip is discharged through the resistor and the second electronic switch.
