Patent ID: 8115345

Claim:
An apparatus for controlling timing of switch operation in a switched circuit, the apparatus comprising: a first switch controller having a plurality of first switch controller outputs, wherein the first switch controller is configured to receive a first switch controller control signal and a second timing signal and is configured to control operation of at least one switch of a first switch set in the switched circuit according to a function of the second timing signal and the first switch controller control signal via at least one of the first switch controller outputs; a second switch controller having a plurality of second switch controller outputs, wherein the second switch controller is configured to receive a second switch controller control signal and a first timing signal and is configured to control operation of at least one switch of a second switch set in the switched circuit according to a function of the first timing signal and the second switch controller control signal via at least one of the second switch controller outputs; a first circuit coupled to at least one of the first switch controller outputs of the first switch controller and configured to receive a control signal to provide the first timing signal to the second switch controller according to a function of the control signal such that the first timing signal is determined by the first circuit in response to at least one of the first switch controller outputs; and a second circuit coupled to at least one of the second switch controller outputs of the second switch controller and configured to receive the control signal to provide the second timing signal to the first switch controller according to a function of the control signal such that the second timing signal is determined by the second circuit in response to at least one of the second switch controller outputs.
