Abstract:
1. A circuit for regulation, comprising: a pulse modulation circuit that is arranged to provide a pulse modulation output signal based, in part, on an output signal; and a synchronous switch control circuit that is arranged to provide a synchronous switch control signal such that the synchronous switch control signal is based, in part, on the pulse modulation output signal; assertion of the synchronous switch control signal is disabled, substantially during a discontinuous conduction mode associated with a switch node current at a switch node; and such that the assertion of the synchronous switch control signal is enabled, substantially during a continuous conduction mode associated with the switch node current, wherein the pulse modulation circuit and the synchronous switch control circuit are configured to operate with a first switch circuit and a synchronous switch circuit coupled together at the switch node to enable regulation of the output signal.
