System for controlling and monitoring an array of point-of-load regulators by a host
DC CAFCFirst Claim
1. A power control system for a host, comprising:
- a plurality of point-of-load (POL) regulators providing regulated power to corresponding loads of the host;
at least one serial data bus operatively connected to said plurality of POL regulators; and
a system controller connected to said at least one serial data bus and adapted to send and receive digital data to and from said plurality of POL regulators, the system controller having a host interface adapted for communications with the host via a communication channel that is separate from said at least one serial data bus;
wherein, programming, control and monitoring information is carried on said at least one serial data bus between said system controller and said plurality of POL regulators, the programming, control and monitoring information being selectively communicated between the system controller and the host via the host interface.

Abstract
A power control system comprises a plurality of POL regulators, at least one serial data bus operatively connecting the plurality of POL regulators, and a system controller connected to the serial data bus and adapted to send and receive digital data to and from the plurality of POL regulators. The serial data bus further comprises a first data bus carrying programming and control information between the system controller and the plurality of POL regulators. The serial data bus may also include a second data bus carrying fault management information between the system controller and the plurality of POL regulators. The power control may also include a front-end regulator providing an intermediate voltage to the plurality of POL regulators on an intermediate voltage bus.

45. A power control system for a host, comprising:
-
at least one point-of-load (POL) regulator providing regulated power to at least one corresponding load, said at least one POL regulator comprising a POL controller and a POL memory device for storing initial configuration data; at least one serial data bus operatively connected to said at least one POL regulator; and a system controller comprising a memory device for storing said initial configuration data and a host interface adapted for communications with said host, said system controller being connected to said at least one serial data bus and adapted to send said initial configuration data to said at least one POL regulator at a start-up of said system controller; wherein, said POL controller is adapted to use at least a portion of said initial configuration data to determine at least one parameter of said regulated power, and digital data concerning said at least one POL regulator is selectively communicated between said system controller and said host via said host interface. - View Dependent Claims (46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68)
