Abstract: The present disclosure includes programmable snubber circuits and methods. In one embodiment, a circuit is configured between first and second power supply terminals. A programmable snubber circuit may be configured between the first and second power supplies to reduce ringing on the power supplies. In one embodiment, the circuit is a switching regulator and the power supply terminals are internal power supply terminals. The snubber circuit may be programmed to reduce ringing caused by switching currents through parasitic inductances in a package.
