Beschreibung
Zusammenfassung:	The invention provides a method for reducing switching oscillation in a switching regulator. The switching regulator comprises two transistors which can not enter a closed state simultaneously. In the invention, a phase-locked loop can be further arranged, and the output frequency of a pulse-width modulation control circuit is equal to setting frequency. Compared with the synchronous switching regulator, the method saves energy consumption and can greatly shorten an oscillating period.
