  • Electric Component with a Protected Current Feeding Terminal
    Publication number: 20060267722
    Abstract: An electric device generates a predetermined amount of heat in the event of a malfunction. The electric device is protected from overheating in that it is arranged, with a fuse in a circuit, such that the fuse and the electric device are thermally coupled to one another, so that the generation of the amount of heat by the electric device causes a fusible material in the fuse to melt. In this manner, the current terminal path of the electric device is interrupted.

  • EMC-optimized power switch
    Patent number: 6404041
    Abstract: The power switch has considerably reduced common-mode interference and relatively reduced circuit complexity. The power switch is formed of a semiconductor chip on a leadframe. A first terminal of the semiconductor chip is connected to the active potential and a second terminal for inactive potential is connected to the leadframe. The second terminal is either the drain of a transistor or the anode of a diode.

  • Switch mode power supply with reduced switching losses
    Patent number: 6388287
    Abstract: The invention relates to a switching transistor presenting reduced switching losses. In the switching transistor, output capacitance is very high when drain/source voltages are low. As the drain/source voltage increases, the capacitance falls to such low values that the energy stored in the transistor becomes very low.
