A power converter controller includes a drive circuit to generate a drive signal to control switching of a power switch. The drive circuit generates the drive signal in response to a current sense signal, a current limit signal, a frequency skip signal, and a hold signal. A current limit generator generates the current limit signal in response to a load. A frequency detection circuit generates the frequency skip signal in response to the drive signal to indicate when an intended frequency of the drive signal is within a frequency window. The current limit signal remains fixed for at least a switching cycle when the intended frequency is within the frequency window. A first latch generates the hold signal to control the current limit generator to hold the current limit signal. The first latch generates the hold signal in response to the frequency skip signal and a feedback signal.
