Abstract
A power transistor module includes a power transistor device and a control circuit. The control circuit is electrically connected to the power transistor device for providing at least one gate voltage to drive the power transistor device, and adjusting the at least one gate voltage in response to an output power of the power transistor module. When the output power is greater than a predetermined power load, the at least one gate voltage has a first swing amplitude; and when the output power is less than or equal to the predetermined power load the at least one gate voltage has a second swing amplitude less than the first swing amplitude.
