Abstract
Disclosed are devices, apparatus, circuitry, components, mechanisms, modules, units, systems, and processes for controlling a power switch of a voltage regulator. A capacitor is coupled to an output of the power switch. Charge delivery circuitry is coupled to the capacitor and configured to provide a charging current to the capacitor. Charge control circuitry can be coupled to the charge delivery circuitry and configured to selectively allow the providing of the charging current to the capacitor.
