Abstract
A driving circuit and a driving method are provided. According to embodiments of the present disclosure, a power switch is driven by constant voltage or constant current during different time periods. The power switch is driven by using a first driving current during a Miller platform period, and the power switch is driven by using a second driving current when the Miller platform period ends, where the first driving current is less than the second driving current, so as to optimize EMI, reduce loss and improve efficiency.
