Abstract
A switching regulator circuit and a method for providing a regulated output voltage for a load is provided that includes a comparator, whose comparator output signal is routed to a first oscillator control input, whereby a first comparator input voltage is present at a first input of the comparator and a second comparator input voltage is present at a second comparator input of the comparator, an oscillator with the first oscillator control input, at which the comparator output signal of the comparator is present, and whereby an oscillator output signal can be provided at an output of the oscillator, and by means of the signal the switching processes at a switching element can be controlled, by which a coil current can be influenced by a coil connected to the switching element, and a first compensator for influencing the second comparator input voltage as a function of the input voltage, whereby this first compensator is connected to the second comparator input of the comparator.
