Abstract
A high-speed feedback circuit for use with, particularly, a buck or buck derived regulator (power processor). The circuit employs a voltage developed by the regulator after the switch and before the filter. From the voltage a current is developed which is combined with (subtracted from) a reference current. The combined current is integrated in a capacitor to develop a voltage used to drive the switch.
