Abstract: A circuit is for controlling a power transistor of a DC/DC converter. The circuit may include first and second first transistors coupled in series between a first reference voltage and a control terminal of the power transistor, the first and second transistors defining a first junction node. The circuit may include third and fourth transistors coupled in series between the control terminal and a second reference voltage, the third and fourth transistors defining a second junction node. The first and second transistors may have a first conductivity type different from a second conductivity type of the third and fourth transistors. The circuit may include a capacitive element coupled between the first and second junction nodes.
