Claim:
1. A control device in a switched electrical power supply system that controls a DC/DC converter of said switched electrical power supply system, said control device comprising: a first input terminal and a second input terminal; a first transistor connected via a source thereof to the second input terminal, a gate of the first transistor being configured to receive control signals originating from a controller; a second transistor connected via a drain thereof to the first input terminal, a source thereof being connected to a drain of the first transistor; a control assembly connected between a gate of the second transistor and the second input terminal, the control assembly including a capacitor and a voltage clipping/routing device connected in series to said capacitor; and a Zener diode having a cathode connected to the gate of the second transistor and an anode connected to the source of the second transistor, wherein the gate of the first transistor is connected to a terminal that is separate from gate connections to the second transistor.
