Abstract
A circuit includes a first transistor having a first current electrode coupled to a first power supply node, a second current electrode coupled to a switching node; a second transistor having a first current electrode coupled to the switching node, a second current electrode coupled to a second power supply node; an inductor having a first terminal coupled to the switching node, a second terminal coupled to an output node; a third transistor having a first current electrode coupled to the output node, a second current electrode coupled to the switching node; a driver circuit configured to transition the switching node from a first voltage to a second voltage by turning on the third transistor to couple the output node to the switching node during a first time period, turning on the first transistor to couple the first power supply node to the switching node during a second time period.
