Abstract

A converter circuit may require sensing an average current as feedback for regulating the average current supplied to a load. Sensing the average current may be inaccurate due to the non-ideal behavior of devices in the converter circuit. The disclosed circuits and methods help to improve the accuracy of the sensed average current by ignoring portions of a PWM cycle. Some of the ignored portions are based on a peak threshold for a rising current of a PWM cycle and a valley threshold for a falling current of a PWM cycle. The peak threshold and the valley threshold may be adjusted to control the average current and the switching frequency of the converter circuit.
