Abstract
A system and method is provided for providing a deadband switching time delay. One embodiment of the present invention includes a switching regulator system. The switching regulator system includes a control circuit configured to alternately activate a high-side power switch and a low-side power switch of the switching regulator system. The switching regulator system also includes a switching delay element configured to provide a switching deadband associated with a logic state transition delay of at least one of the high-side power switch and the low-side power switch, the delay element comprising a programmable coarse delay element to provide a course delay amount and a programmable fine delay element to provide a fine delay amount.
