Abstract
An adaptive pulse positioning system for a voltage converter providing an output voltage, the system including a PWM generation circuit, a sensor, and a pulse positioning circuit. The PWM generation circuit generates a PWM signal with PWM pulses for controlling the output voltage of the voltage controller. The sensor senses an output load condition of the voltage converter and provides a load signal indicative thereof. The pulse positioning circuit adaptively positions the PWM pulses based on the load signal. A method of adaptively positioning PWM pulses that are used to control an output voltage of a voltage regulator including generating a series of PWM pulses based on a clock signal, sensing an output load condition, and adaptively shifting the series of PWM pulses based on the output load condition.
