Abstract
A switching regulator that actively snubs waveforms is provided. The switching regulator includes an inductor, a power switch electrically coupled to the inductor, a first diode electrically coupled to the inductor, and a snubber circuit being coupled in parallel to the inductor. The power switch and the snubber circuit include break-before-make switches such that the power switch is closed only after the snubber switch is opened to initiate a switching cycle, and the snubber switch is closed only after the power switch is opened to provide a decay path for snubbing ringing waveforms.
