Abstract
In one embodiment, a method is provided for delivering optimal charge bursts in a voltage regulator under light load conditions. The method includes: in an initial period, determining an optimal turn-on time for a high-side switch of the voltage regulator to produce a desired voltage ripple; and in steady-state operation, turning on the high-side switch for approximately the optimal turn-on time, thereby delivering optimal charge bursts for the desired voltage ripple in the voltage regulator.
