Abstract
Embodiments for methods and apparatuses for controlling a skew time of switches of a switching voltage regulator are disclosed. One method includes generating a switching voltage through closing and opening of a series switch and a shunt switch as controlled by a series switch control signal and a shunt switch control signal. An error signal is generated that is proportional to a relative displacement of an on-interval of the series switch and an off-interval of the shunt switch. A relative delay of the series switch control signal and the shunt switch control signal is adjusted based on the error signal, and a regulated output voltage is generated based upon the switching voltage.
