PURPOSE: To maintain the peak value of current detection signals larger than the amplitude of turn-on noise even under a light load, by switching current detection gain through opening/closing of a first switch connected with a resistor in a current detection circuit.KOHAMA TATSUO...
Current-mode control is an alternative method for regulating output voltage in a DC/DC converter. The goal is to achieve a constant output voltage from a switchingDC/DC converterby measuring the current passing through the inductor. This should not be confused with current regulation, or constant...

This paper introduces a digital average current-mode controller architecture based on a low-resolution current A/D converter and a simple digital controller realization. The proposed approach combines advantages of practical digital realization and current-mode control for DC-DC converters operating at hi...
