Abstract

Methods, systems, and apparatus to facilitate current sensing for valley current-controlled power converters are disclosed. An example apparatus includes a comparator including a first terminal, a second terminal, and an output. The apparatus further includes a first transistor including a first drain coupled to the first terminal of the comparator. The apparatus further includes a second transistor including a second drain coupled to the first terminal of the comparator. The apparatus further includes a third transistor including a third drain coupled to the second terminal of the comparator.
