Classification: CPC H | IPC H

Claim 0:
1. A power converter including:
(a) a converter circuit configured to convert an input voltage VIN to a different output voltage VOUT;
(b) a control block for disabling operation of the converter circuit;
(c) a voltage node VX between the converter circuit and the output VOUT;
(d) a VIN detection block, coupled to the input voltage VIN and to the control block, and optionally coupled to one of VOUT or the voltage node VX, and configured to detect a voltage drop in the input voltage VIN and generate a control signal to the control block to disable operation of the converter circuit;
wherein the converter circuit is coupled to a source of at least two non-overlapping clock signals having ON states separated by a dead time, and wherein the VIN detection block is configured to detect the voltage drop in the input voltage VIN during the dead time.
