Abstract
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.
