1. An integrated circuit (IC) for use with a voltage converter, comprising:
a fault detector, the fault detector capable to detect one or more fault events during operation of the voltage converter and generate one or more fault signals with respect to the one or more to be detected fault events;
wherein the voltage converter to comprise at least a set of switches and a set of capacitors arranged to form a configuration such that at least some of the switches operate in a manner to form an electrical connection of at least some of the capacitors to respective alternate voltages in successive stages of operation of the voltage converter, and
wherein the voltage converter to comprise a disconnect switch to have a drain-to-source (DS) voltage rating greater than an input voltage of the voltage converter and greater than a DS voltage rating of at least one switch in the set of switches;
wherein the one or more fault signals to signal the disconnect switch to electrically disconnect through at least one switch in the set of switches.
