1. Voltage controller for a pulsed load, in particular for a mobile-telephone or telematics transmitter having a control element (21) which is connected between an input connection (22) for the application of an input voltage (Vin) and an output connection (23) for supplying an output voltage (Vout) to a pulsed load (14), a comparison element (24) which compares an actual value signal (Vo) corresponding to the output voltage (Vout) with a desired value signal (Vref) and supplies a control signal (Vc) to the control element (21) in order to influence the output voltage (Vout) to the effect of adapting the actual value signal (Vo) to the desired value signal (Vref), and a desired value circuit (26, 26

  • ) which derives the desired value signal (Vref) from the input voltage (Vin) in such a way that it is substantially constant over the duration of a load pulse.
