Abstract
A switching regulator target voltage is adjusted to a first value corresponding to a pre-charge voltage that is present at a regulator output terminal. The switching regulator responds to a comparison signal resulting from a comparison of the target voltage and a feedback voltage. When the switching regulator is on, the target voltage is adjusted to a second value corresponding to a nominal regulator output voltage. In one embodiment, a synchronous switch is disabled when a lockout circuit receives a disable signal. The lockout circuit is unlocked when an enable signal is provided by a switching controller.
