Abstract:
A method detects current-limit events indicating a maximum current threshold of a switching converter has been reached, A compensation voltage is adjusted in response to the detected current-limit events, where the compensation voltage defines a duty cycle of the switching converter. A time for which no current-limit events have been detected is sensed, and the value of the compensation voltage adjusted in response to the detected time reaching a time step threshold.
