An EMI reduction technique using two MOSFETs instead of a single MOSFET in a step-down converter is investigated in this article. A circuit that implements this technique together with external capacitor control was designed and measurement results were compared against simulations. The switching element in the proposed circuit is an IRF7309 that consists… CONTINUE READING
