Abstract

See full text

A voltage converter includes an inductor, a transistor, a comparator, an error amplifier, and a slope generator circuit. The transistor has a control input and first and second transistor current terminals. The first current terminal is coupled to the inductor. The comparator has first and second comparator inputs and a comparator output. The comparator output is usable to control the transistor's control input. The error amplifier has an error amplifier input and an error amplifier output. The error amplifier output is coupled to the first comparator input. The slope generator circuit is coupled to at least one of the first or second comparator inputs. The slope generator circuit is configured to generate a slope compensation current which, during at least a portion of each cycle of operation of the voltage regulator, varies approximately exponentially with respect to time.
