Abstract:
1. An apparatus including circuitry for providing a signal indicative of instances of conduction of average inductor current in a DC-to-DC voltage converter, comprising: first timing control circuitry responsive to at least a control signal having a signal period P and related to a current conduction of an inductor of a DC-to-DC voltage converter by providing a first timing signal that transitions between first and second signal states substantially as said current conduction transitions between increasing and decreasing current conduction intervals, wherein said signal period P is an inverse of a switching frequency of said DC-to-DC voltage converter; and second timing control circuitry responsive to at least one of said control signal and said first timing signal by providing a second timing signal that transitions between third and fourth signal states approximately halfway through one of said increasing and decreasing current conduction intervals.
