    Abstract: This application relates to methods, apparatus, and systems for throttling a subsystem of a computing device, when a current demanded by the subsystem exceeds a threshold value, in order to protect a power supply providing the current to the subsystem. By reducing the current demanded by the subsystem, the subsystem can be powered by a power supply having a smaller dynamic current range than the subsystem, thereby removing the need to provide a larger power supply for the subsystem. The demand current is measured before the current provided by the power supply significantly increases and a transient current source providing current to the subsystem is depleted. In this way, the subsystem can be throttled before the power supply is aware of an increase in the current demand.

    Abstract translation: 本申请涉及当子系统要求的电流超过阈值时,为了保护向子系统提供电流的电源,节流计算设备的子系统的方法,装置和系统。 通过减少子系统所需的电流,子系统可以由动力电流范围小于子系统的电源供电,从而不需要为子系统提供更大的电源。 在电源提供的电流显着增加并且向子系统提供电流的瞬态电流源耗尽之前测量需求电流。 这样,在电源意识到当前需求增加之前,子系统可以节流。
