摘要： The present technology is related generally to a switching mode power supply with virtual current sensing. The switching mode power supply comprises a power stage that includes a first power switch and a second power switch coupled in series. The switching mode power supply senses a first current flowing through the first power switch during on-time and provides a virtual current sense signal that is proportional to a second current flowing through the second power switch during on-time. The switching mode power supply further combines the real current sense signal and the virtual current sense signal to form a current sense signal, which is sent to the controller to realize desired control.

摘要： 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.
