Classification: CPC H | IPC H

Claim 0:
1. An apparatus, comprising:
an inductor coupled between an input power supply node and a switch node;
a converter circuit configured to generate a particular voltage level on a boost node using a voltage level of the switch node; and
an output circuit coupled between the boost node and a regulated power supply node, wherein the 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, isolate the boost node from the regulated power supply node; and
in response to a detection of a regulation event, clamp a voltage level between the boost node and the regulated power supply node.
