Abstract
A power conversion circuit is provided. A reference signal is integrated over a first timer period. A second signal is generated that is approximately proportional to an output current of the power conversion circuit. The second signal is integrated over a second time period. A first result of the integration of the reference signal is compared to a second result of the integration of the second signal. A fault signal is asserted if the second result is greater than the first result.
