摘要：
This disclosure describes a protection circuit configured to protect a power converter. The protection circuit may be configured to determine when the power converter is operating in a tristate mode, and upon determining that the power converter is operating in the tristate mode, to disable a supply to the power converter based on a comparison of a switch node voltage on a switch node of the power converter to a feedback node voltage on an output node of the power converter.
