Abstract
A power controller is in use of a power converter whose output voltage can be regulated at a first nominal output voltage or a second nominal output voltage less than the first nominal output voltage. An ON-time controller controls an ON time of a driving signal provided to a power switch according to a compensation signal. A frequency controller controls, based on the compensation signal and a feedback signal, a switching frequency of the driving signal. If the compensation signal has an input waveform and when the output voltage is regulated at the first or second nominal output voltage, the frequency controller provides first or second settling time to stabilize the switching frequency, respectively. The second settling time is longer than the first settling time.
