Abstract

A low gain feedback compensation circuit is provided on an integrated circuit. The feedback compensation circuit is coupled to a step down power supply on the integrated circuit. The step down power supply is operable to receive an input voltage and to generate an output voltage based on the input voltage. The feedback compensation circuit includes a line regulation circuit. The line regulation circuit is operable to receive the input voltage and a reference voltage. The line regulation circuit is also operable to generate an offset voltage based on the input voltage and the reference voltage.
