Abstract
The techniques and circuits, described herein, include solutions for pass-through operation including overcurrent protection in buck-boost converters. In some aspects, first and second switches selectively couple inputs of a peak current comparator to inputs of an error amplifier during pass-through operation. As part of peak current control scheme, one of the peak current comparator inputs is coupled to a current sensor that senses a current through an inductor of the buck-boost converter. As a result, an output of the error amplifier tracks the inductor current during pass-through mode, which may be utilized to implement inductor overcurrent protection in the pass-through mode.
