Abstract: A system includes a switching converter circuit and a monitoring circuit coupled to the switching converter circuit. The monitoring circuit includes a current estimation circuit configured to estimate an output current of the switching converter circuit. The monitoring circuit also includes a compare circuit configured to compare the estimated average output current with a threshold, wherein the compare circuit is configured to output an alert signal in response to the estimated output current being greater than the threshold.
