A voltage converter includes, among other things, an amplifier, a voltage
combiner, and a hysteretic comparator. The amplifier has a first input
terminal which receives a first voltage representative of an output
voltage of the voltage converter, a second input terminal which receives
a first reference voltage, and an output terminal which generates a
second voltage proportional to a difference between the first voltage and
the first reference voltage. The voltage combiner combines the second
voltage with a second reference voltage to generate a combined voltage.
The comparator causes a third voltage to decrease if a feedback voltage
defined by the third voltage is detected by the comparator as being
greater than a first threshold voltage defined by the combined voltage,
and further to cause the third voltage to increase if the feedback
voltage is detected by the comparator as being less than the first
threshold. The third voltage is applied to a first terminal of a load
external to the voltage converter.
