Abstract
An adaptive pulse positioning system for a voltage converter including an adjustable ramp generator, a pulse generator circuit, and a sense and adjust circuit. The adjustable ramp generator has an adjust input and provides a periodic ramp voltage having an adjustable magnitude based on an adjust signal provided to the adjust input. The pulse generator circuit receives the ramp voltage and generates a pulse signal with control pulses for controlling the output voltage of the voltage controller based on the ramp voltage. The sense and adjust circuit senses an output load transient and provides the adjust signal to the adjust input of the ramp generator to adaptively shift the pulse signal in time in response to the output load transient without adding pulses to the pulse signal.
