Abstract
A control method for a switching converter with a main switch and a sync switch and converting an AC (alternating current) input voltage into an output voltage. The control method includes the following steps. 1) Determining whether the switching converter works in DCM or CRM. 2) When the switching converter works in CRM, turning off the sync switch when a first time period started from the time when an inductor current decreases to zero expires. 3) Turning on the main switch at a valley of a voltage across the main switch. And 4) turning off the main switch when an on time of the main switch reaches a second time period, where the second time period is related to the first time period.
