Abstract
The instant disclosure provides an intelligent pulse control circuit used for a power supply. The intelligent pulse control circuit comprises a control unit, a buffer unit, a comparing unit and a switch unit. The buffer receives a loading signal. The comparing unit is coupled to the buffer unit, receives the loading signal generated according to the current of the output loading, and compares the loading signal and the feedback signal to generate a control signal. The switch unit is controlled by the control signal of the comparing unit to provide a turn-off signal. When the output loading is light load, the switch unit controls the control unit to disable the PFC stage and the PWM stage according to the turn-off signal. Accordingly, the intelligent pulse control circuit can reduce the power consumption when the output loading is light load.
