Abstract:
The present technology discloses a switching mode power supply with predicted PWM control. In one embodiment, the switching mode power supply monitors the slew rate of COMP signal which represents the output voltage of the switching mode power supply. When the load steps up, the ON state of the power stage is prolonged; when the load steps down, the power stage is turned off earlier.
