App note from Cirrus about overshoot/ringing suppression in the output stage of Class-D amplifiers using RC Snubber. Link here (PDF) High speed switching of power MOSFETs in the power stage of Class-D amplifiers results in output voltage over/undershoot and high frequency ringing on the output waveform. The over/undershoot places additional stress on the power MOSFETs, […]

RC snubber calculator spreadsheet
Paulo has developed a free RC snubber calculator, an Excel-based calculator eases the design of RC snubbers in power switching applications: In power switching applications, a designer often has to contend with spurious oscillations. These are the result of parasitic capacitances and inductance on the board and behave like the step response of an RLC […]
