Abstract
A controller for a power converter comprising a drive circuit and an adaptive current limit generator. The drive circuit is coupled to receive a request signal representative of a power demand of an output of the power converter. The drive circuit is configured to generate a drive signal to control switching of a power switch in response to the request signal. The adaptive current limit generator configured to generate a current limit signal and the drive circuit is configured to turn off the power switch when a current sense signal reaches the current limit signal. The adaptive current limit generator is configured to vary an upper threshold of the current limit signal to a first value when a switching frequency is less than a frequency threshold and vary the upper threshold to a second value when the switching frequency is greater than the frequency threshold.
