摘要：
A controller for controlling a switching power converter having an input for receiving a periodic input signal and an output for providing a substantially constant output voltage to a load includes a monitor device configured to compare a switching time interval or a switching frequency with a predetermined threshold value to obtain a comparison result and a parameter recorder configured to record an entry criteria in response to the comparison result, wherein the entry criteria indicates a transition of the switching power converter from a variable switching frequency state to a constant switching frequency state.
