Abstract
In some embodiments, powered devices, circuits, and methods are disclosed that may include biasing a hot swap switch to couple a capacitor of a DC-DC converter to negative supply node when an input voltage exceeds a threshold and biasing a telephony switch to couple a positive supply node to a negative supply node when the input voltage exceeds the threshold. Further, the method may further include deactivating the hot swap switch after a period of time, and continuing to bias the telephony switch.
