集成电路的功率分配控制的系统及方法
摘要：
本发明揭示一种装置，其包含：第一引脚，用以向集成电路的第一功率域供应功率；第二引脚，用以向所述集成电路的第二功率域供应功率；切换调节器；以及控制器。所述切换调节器耦合到所述第一引脚以向所述第一功率域提供第一经调节的功率供应，且耦合到所述第二引脚以向所述第二功率域提供第二经调节的功率供应。所述控制器耦合到所述第一引脚和所述第二引脚，以在低功率事件期间选择性地减少到达至少所述第二引脚的电流流动。
摘要（英）：

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.
