Original Abstract Submitted
This disclosure describes a filter circuit for a power converter circuit. The filter circuit may comprise a comparator circuit configured to determine when a switch node voltage of the power converter circuit satisfies a voltage threshold, and a deglitch circuit configured to determine whether the switch node voltage satisfying the threshold is expected based on control signals to the power converter circuit or attributable to a situation of ringing on an inductor of the power converter circuit. The filter circuit may be configured to output a fault in response to both the comparator circuit determining that the switch node voltage of the power converter circuit satisfies the voltage threshold and the deglitch circuit determining that the switch node voltage satisfying the threshold is not expected based on the control signals and not attributable to the situation of ringing on the inductor of the power converter circuit.
