Abstract
A method for providing a jitter signal for modulating a switching frequency of a power switch for a power converter. The method comprising receiving a drive signal representative of the switching frequency of the power switch, detecting the switching frequency from the drive signal, determining if the switching frequency is less than a first threshold frequency, and modulating a frequency of the jitter signal in response to determining if the switching frequency is less than the first threshold frequency.
