Abstract
A voltage regulator circuit comprises a switching circuit, a dynamic clamp circuit, and a comparison circuit. The switching circuit adjusts a switching duty cycle to produce a regulated output voltage using an error signal representative of a difference between a target voltage value and the output voltage. The dynamic clamp circuit determines a maximum peak inductor current command value using the output voltage and an input voltage of the voltage regulator circuit. The comparison circuit sets a maximum peak inductor current value using the maximum peak inductor current command value and a slope compensation current, wherein the maximum peak inductor current value is constant for different values of output voltage. The comparison circuit compares a sensed inductor current to a peak inductor current value and enables switching of the voltage regulator system according to the comparison.
