Abstract
The present invention employs a pin of a controller to set an over current protection value and a time period respectively by means of time-division and/or voltage and current. Therefore, the cost of the controller is reduced due to reducing the amount of pins thereof. Furthermore, the time period is not only used to setting a constant on time, but also used to setting a constant off time and an operating frequency for different controlling mode.
