Abstract
A DC-DC converter including voltage and slope regulation and a method of operating the same are provided. Generally, the converter includes a voltage source to supply an output, a switching-circuit coupled to the voltage sources to control a voltage on the output, and a slope-detector coupled to the switching-circuit and the output to detect a slope of a voltage transition between a first and a second voltage. When the detected slope exceeds a predetermined maximum the slope-detector sends a digital signal to the switching-circuit to intermittently pause the voltage transition to limit the slope to less than the maximum. In one embodiment, the voltage source is a charge-pump, and the switching-circuit includes a logic-gate coupled to the slope-detector to turn the charge-pump ON when the detected slope is less than the maximum, and to turn OFF the charge-pump for a time when the slope exceeds the maximum.
