Example Embodiment
[0079] The technical solution in this application will be described below in conjunction with the drawings.
[0080] It should be understood that the embodiments of the present invention can be applied to a DC to DC voltage conversion scenario. Specifically, the embodiment of the present invention can be applied to a buck converter, such as a BUCK circuit, and can also be applied to a boost converter, such as a Boost circuit, which is not limited in the embodiment of the present invention.
[0081] figure 1 A typical BUCK circuit 100 is shown, which can be used to perform step-down conversion of the input voltage and provide it to the load R. Such as figure 1 As shown, the BUCK circuit 100 includes: an input terminal I, a power tube switch 110, a power tube switch 110, an inductor 130, a capacitor 120, and output terminals O1 and O2, wherein the inductor 130 and the capacitor 120 form a filter circuit. Specifically, one end of the power tube switch 110 is connected to the input te...
