Abstract
Circuitry and method for providing a signal indicative of instances of conduction of average inductor current in a DC-to-DC voltage converter. Such signal identifies a time when the instantaneous average current being conducted by the inductor in a DC-to-DC voltage converter can be measured by providing a signal edge approximately halfway through one of the increasing and decreasing current conduction intervals of the inductor.
