Summary: | A controller for use in a power converter comprising a comparator, request control, and foldback control. The comparator configured to receive a feedback signal representative of an output of the power converter and a first regulation reference representative of a target value for the output, and in response to the comparison of the feedback signal and the first regulation reference, generate a first regulation signal. Request control configured to receive the first regulation reference, and output a request signal with request events. Foldback control configured to receive the first regulation signal to generate the first regulation reference, the foldback control further configured to sense a foldback or fault condition if the feedback signal is less than the first regulation reference for a threshold duration of time, the foldback control further configured to vary the first regulation reference in response to the sensed foldback or fault condition to reduce the output. |
