Abstract: A method and apparatus for augmenting an external voltage regulator with a shunt integrated voltage regulator is disclosed. In one embodiment, an integrated circuit (IC) includes a load circuit coupled to a supply voltage node. The supply voltage node is electrically coupled to receive a supply voltage from an external voltage regulator. The IC also includes a shunt integrated voltage regulator coupled to the supply voltage node and implemented on the same IC die as the load circuit. If the supply voltage falls below a specified value (e.g., to increased current demand), the integrated voltage regulator may begin supplying current to the load. This may cause the supply voltage to return to within its specified range of the specified value, while allowing the external voltage regulator sufficient time to respond to the increased current demand. Thus, voltage droops on the supply voltage node may be minimized.
Abstract translation: 公开了一种用于利用分流集成稳压器增强外部电压调节器的方法和装置。 在一个实施例中,集成电路(IC)包括耦合到电源电压节点的负载电路。 电源节点电耦合以从外部电压调节器接收电源电压。 IC还包括耦合到电源电压节点并在与负载电路相同的IC管芯上实现的分流集成稳压器。 如果电源电压低于指定值(例如,增加电流需求),集成稳压器可能开始向负载提供电流。 这可能导致电源电压恢复到指定值的指定范围内,同时允许外部电压调节器有足够的时间来响应增加的电流需求。 因此,电源电压节点上的电压下降可以被最小化。

Abstract: A power management circuit included in a computer system regulates a voltage level of a power supply node used by other circuits in the computer system. The power management circuit includes a control circuit and multiple phase circuits coupled to the regulated power supply node via corresponding inductors. The control circuit selectively activates particular ones of the multiple phase circuits allowing them source respective currents to the regulated power supply node. The control circuit also selectively activates particular ones of other phase circuits that are external to the power management circuit and coupled to the regulated power supply node via their own corresponding inductors. Once activated, the external phase circuits source respective currents to the regulated power supply node via their corresponding inductors.

Abstract: A power management subsystem included in a computer system may include a host device and a power circuit group. The power circuit group includes multiple power circuits arranged in a tree-like structure. The resources of the multiple power circuits are mapped to corresponding addresses within a common address space. The host device sends, via a first communication bus, commands to a branch power circuit of the multiple power circuits, which, in turn, relays the commands, using a second communication bus, to corresponding ones of the other power circuits based on respective power resources specified in the commands received from the host device.

Abstract: An apparatus includes a control circuit and a voltage regulator circuit coupled to a regulated power supply node. The voltage regulator circuit is configured to generate a power signal on the regulated power supply node using a reference voltage level. The apparatus further includes a control circuit that is configured to determine an operating mode using results of a comparison of a threshold value and a load current being drawn from the regulated power supply node by a load circuit. The control circuit may be further configured to set, in a first operating mode, the reference voltage level independently of the load current, and set, in a second operating mode, the reference voltage level using the load current.
