Abstract
A control circuit for controlling a transistor includes a reference signal generating circuit and a driver stage circuit. The reference signal generating circuit outputs a reference signal, and to control the reference signal having a first change trend in a first time period of a time interval and having a second change trend in a second time period of the time interval based on time. The driver stage circuit is configured to control the transistor according to the reference signal and a current sampling signal, so that the current flowing through the transistor changes with the reference signal.
