Abstract
The novel current-mode switching regulator does not determine the load current by picking off a measurement voltage at a measuring resistor, as in the conventional prior art. Instead, the voltage drop across the inductor which is required in any case is picked off as the measurement voltage. A regulating signal derived from the load current is determined, by integration with respect to time, with a voltage-controlled current source. The regulating signal is fed back, as a regulated variable, into regulators of the inner control loop. In this way, it is possible to dispense with the measuring resistor. An additional compensation device makes it possible, moreover, to compensate for a regulation deviation in the desired potential of the outer control loop.
