Linking separate eFuse and ORING controllers for output overvoltage protection in redundant power converters

Embodiments for linking separate eFuse and ORING controllers for output overvoltage protection in power conversion applications. Voltage regulators are configured in parallel. An input circuit includes an input controller, the input circuit being coupled to an input of at least one voltage regulator of the voltage regulators. An output circuit includes an output controller, the output circuit being coupled to an output of the at least one voltage regulator. The output controller is coupled to the input circuit to cause the input circuit to prevent power to the at least one voltage regulator in response to the output controller detecting an overvoltage condition.
