Abstract
A switch-mode power supply and a zero current detector for use therein. A zero current detector includes an input stage and an output stage. The output stage is coupled to the input stage. The output stage includes a detector output terminal, a first transistor, and a second transistor. The first transistor includes an input terminal and a control terminal. The input terminal is coupled to the detector output terminal. The control terminal is coupled to the input stage. The second transistor includes an input terminal, a control terminal, and an output terminal. The input terminal is coupled to the control terminal of the first transistor. The control terminal is coupled to the input terminal of the second transistor. The output terminal is coupled to ground.
