Abstract (en)

[origin: EP0860762A2] The output voltage ÄUzÜ is generated based upon a variable input voltage ÄUbattÜ. After an initial period the voltage is held at a constant value ÄUnennÜ until a specific voltage reduction has been obtained Ä(U2Ü relative to the input voltage. The voltage control is provided by a regulating stage coupled to a switching circuit.
