Abstract

To facilitate current sensing for valley current-controlled power converters, an example apparatus includes a comparator having a first terminal, a second terminal, and an output. A first transistor has a first drain coupled to the first terminal of the comparator. A second transistor has a second drain coupled to the first terminal of the comparator. A third transistor has a third drain coupled to the second terminal of the comparator.
