Abstract
Various embodiments of the present application are directed towards a buck converter circuit including a controller circuit. In some embodiments, the buck converter circuit includes a first switching device, a second switching device, an inductor, and a controller. The inductor is electrically coupled to a node at which a source/drain terminal of the first switching device and a source/drain terminal of the second switching device are electrically coupled. The controller is configured to alternatingly change the first switching device between ON and OFF, and further configured to alternatingly change the second switching device between ON and OFF. The first switching device is OFF while the second switching device is ON. The first switching device is partially ON immediately before or after the second switching device transitions between ON and OFF.
