Abstract

See full text

The present invention monitors the average switching frequency at the output of the comparator and adjusts the delay compensation accordingly. That is, the switching frequency monitoring circuit looks at the average switching frequency and maintains the average switching frequency in a 'frequency zone' which corresponds to a high elbow and a low noise floor.
