Abstract
A mode switching circuit for a switching power supply having a power switch and a synchronous switch is configured to: control the switching power supply to switch between a first mode and a second mode in response to a transitioning of a load of the switching power supply, in order to suppress overshoot of an output voltage of the switching power supply; where an inductor current of the switching power supply is not less than zero in the first mode; and where the inductor current is allowed to be less than zero in the second mode.
