Abstract
A method for generating an output voltage from an input voltage with a switched mode power supply at a switching frequency is provided. At the switching frequency, a transistor within a switching circuit is deactivated so as to enter into a dead time interval, where the switching circuit includes a switching node. A negative inductor current is used during the dead time interval so as to slew the switching node, where switching frequency and the input voltage are sufficiently large so as to overcome a loss incurred by using the negative inductor current.
