Abstract: Systems and methods described herein correspond to supply harvesting operations. Power management circuitry may receive a supply voltage from other power management circuitry. This supply voltage may be a harvested supply from the other power management circuitry. Moreover, some of the power management circuitry may be operated as controller power management circuitry to supply the supply voltage via one or more rails and some of the power management circuitry may be operated as leaf power management circuitry to harvest the supply voltage from the one or more rails. Leaf power management circuitry may exclude a regulator, enabling that leaf power management circuitry to be entered into a lower power mode than previously enabled when the regulator was included.

Abstract: A power delivery system included in a computer system using multiple power converter circuits to generate respective voltage levels on multiple power supply nodes. The power delivery system includes a step-down power converter circuit that generates a voltage level for use by host and follower power converter circuits. The host power converter circuit generates an external demand current that is shared by multiple follower power converter circuits to regulate the voltage level on the multiple power supply nodes. The power delivery system can be scaled to different platforms of the computer system by adjusting the number of follower power converter circuits.

Abstract: A regulator circuit included in a computer system may include a control circuit and multiple pass circuits that source respective supply currents to a regulated power supply node by adjusting respective conductance values between an input power supply node and the regulated power supply node. The number of pass circuits can be adjusted on a design-by-design basis based on a threshold load current for the regulator circuit or on a threshold conductance between the input power supply node and the regulated power supply node. The control circuit adjusts the respective conductance values using a combination of respective sense currents generated by the multiple pass circuits along with a reference voltage and a voltage level of the regulated power supply node.

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: A scalable battery charger can include a leader charger and at least one follower charger. The leader can include: a DC-DC converter leader phase that receives an input voltage and operates one or more switching devices to generate a regulated output; leader control circuitry that operates the DC-DC converter leader phase to regulate the output; and a leader-follower communication interface that couples the leader control circuitry to the at least one follower charger. The at least one follower charger can include: one or more DC-DC converter follower phases that receive an input voltage and operate one or more switching devices to generate a regulated output; follower control circuitry that operates the one or more DC-DC converter follower phases to regulate the follower output; and a leader-follower communication interface that couples the follower control circuitry to the leader charger.
