Abstract: The present disclosure provides a pair of NMOSFET switches connected in series, an output filter, a control circuit, a boot-strap capacitor and a disabling circuit. A high-side MOSFET switch is coupled to an input voltage. A low-side MOSFET switch is coupled to a ground. The high-side MOSFET switch and the low-side MOSFET switch have complementary duty cycles.
