Abstract
Various methods and devices that involve snubber circuits for switching power converters are disclosed. An example power converter has a snubbing circuit. The snubber circuit comprises a bypass capacitor connecting an input node of the power converter to a ground node of the power converter, a decoupling capacitor that connects the input node of the power converter to a snubber node, and a snubbing resistor that connects the snubber node to the ground node. The snubbing resistor connects the decoupling capacitor to the ground node of the power converter. The snubbing resistor is greater than 1 ohm. The decoupling capacitor is greater than 5 nanofarads and less than 0.5 microfarads. The bypass capacitor is greater than 1 microfarads.
