Abstract

The present invention relates to a system and method for power distribution control of integrated circuits. The invention discloses a device, which comprises: a first pin used to supply power to a first power domain of an integrated circuit; a second pin used to supply power to a second power domain of the integrated circuit; a switching regulator devices; and controllers. The switching regulator is coupled to the first pin to provide a first regulated power supply to the first power domain and to the second pin to provide a second power supply to the second power domain. Regulated power supply. The controller is coupled to the first pin and the second pin to selectively reduce current flow to at least the second pin during a low power event.
