Abstract
A disconnect switch for a power converter is disclosed. An apparatus includes an inductor coupled between an input power supply node and a switch node, and a converter circuit configured to generate a particular voltage level on a boost node using a voltage level of the switch node. An output circuit is configured to provide the particular voltage level on the regulated power supply node using a voltage level of the boost node. In response to a determination that the regulated power supply node has been shorted to ground, the output circuit is configured isolate the boost node from the regulated power supply node. In response to a detection of a regulation event, the output circuit is configured to reduce the voltage level of the boost node to generate a reduced voltage on the regulated power supply node.
