Abstract:

A device is disclosed that includes a first pin to supply power to a first power domain of an integrated circuit, a second pin to supply power to a second power domain of the integrated circuit, a switching regulator and a controller. The switching regulator is coupled to the first pin to provide a first regulated power supply to the first power domain and is coupled to the second pin to provide a second regulated power supply to the second power domain. The controller is coupled to the first pin and to the second pin to selectively reduce current flow to at least the second pin during a low power event.
