Abstract
A switching converter and method for controlling a switching converter in a quasi resonant mode of operation, wherein a sense voltage is predefined for a PWM controller to determine a switch off time of a switching element, a switch-on time of the switching element also falls in a valley of an oscillating voltage that is being applied to the switched-off switching element, and where the sense voltage is reduced in each valley occurring after a switch-off operation such that a stable operating point is thus reached under any load.
