ABSTRACT:
For use with a controller, couplable to a network of first and second comparators, that disables a power converter an actual output current thereof exceeds a threshold output current, an integrated protection circuit and method of operating the same. In one embodiment, the integrated protection circuit includes: (1) a sensor that senses an actual input voltage of the power converter and (2) an isolation circuit, coupled to the first comparator, that selectively decouples the first comparator from the controller, the second comparator causing the controller to disable the power converter when the actual input voltage falls below a threshold input voltage thereby allowing the protection circuit to provide both overcurrent and undervoltage protection.
