專利摘要(英)
A driving circuit for a power transistor is proposed and includes a gate driving circuit, a controlling circuit and the power transistor. The gate driving circuit outputs a driving voltage signal and a pulse width modulation signal. The controlling circuit is coupled to the gate driving circuit and includes a voltage controller, a first transistor and a second transistor. The voltage controller outputs a controlling signal. The first transistor is turned on or off according to the pulse width modulation signal. The second transistor is turned on or off according to the pulse width modulation signal and the controlling signal. The power transistor coupled to the gate driving circuit and the controlling circuit is controlled by the driving voltage signal. When the first transistor is turned on or the first transistor and the second transistor are turned on, the driving voltage signal is pulled to a target voltage level.
