Abstract
Methods and apparatus for a self-tracking high-side pre-driver control are described. In an example, a method is described comprising charging a first terminal associated with a first capacitive element to a first voltage with respect to ground and a second terminal associated with a second capacitive element to a second voltage with respect to ground, changing the first voltage and the second voltage with respect to ground by changing a swing voltage, selecting one of the first voltage or the second voltage based on a first switched-mode power supply topology or a second switched-mode power supply topology and driving a transistor using the selected voltage.
