Beschreibung
Zusammenfassung:	A driving circuit providing a driving signal at a driving terminal to drive a power switch. The driving signal has a first driving period and a second driving period. Both the first driving period and the second driving period have a first driving time interval. The driving circuit has a first equivalent on resistor established during the first driving time interval and located between a first voltage node and the driving terminal. The first equivalent on resistor has a first equivalent on resistance during the first driving time interval of the first driving period and has a second equivalent on resistance during the first driving time interval of the second driving period. The first equivalent on resistance and the second equivalent on resistance are not equal.
