Abstract
A powered device includes a voltage protection circuit, two outputs, a switch, and a snubber circuit. The two outputs of the integrated circuit may be coupled to an external transformer. The snubber circuit of the integrated circuit is responsive to the switch and is coupled with respect to the two outputs to direct energy from at least one of the two outputs to the voltage protection circuit.
