Abstract
A switching power supply comprises a power converter having a transformer, a low side switch configured to draw current from a supply voltage through a primary winding of the transformer and a high side switch configured to couple the primary winding of the transformer to a snubber capacitor. A controller is configured to synchronously control the opening and closing of the low side switch and the high side switch so as to form a regulated output voltage. A first voltage is generated at a node between the low side switch and the high side switch. The controller is further configured to open the high side switch during each switching cycle when the first voltage reaches a determined level. The determined level is higher than the supply voltage by an amount that is adjusted dependent on a monitored level of the supply voltage.
