Abstract
A switching power supply comprises a power converter that includes a transformer, a low side switch and a high side switch. The low side switch draws current from a supply voltage through a primary winding of the transformer. The high side switch discharges current from the primary winding of the transformer to a snubber capacitor. The controller synchronously controls the opening and closing of the low side switch and the high side switch. The power converter can be included in a flyback converter. The power converter can generate a regulated output voltage.
