Abstract
Embodiments for at least one method and apparatus for controlling timing of switch control signals of a switching voltage regulator disclosed. One method includes generating a regulated output voltage based upon a switching voltage, generating the switching voltage through controlled closing and opening of a series switch element and a shunt switch element, and controlling, by a delay block, the closing and opening of the series switch element and a shunt switch element. The delay block control includes receiving, by the delay block, a timing signal, generating a one of a series switch control signal and a shunt switch control signal by controllably delaying the timing signal with a first delay, and generating one other of the series switch control signal and the shunt switch control signal by inverting, and controllably delaying the timing signal with a second delay.
