Voltage Regulator-Down 11.0: Processor Power Delivery Design Guide
Voltage Regulator-Down (VRD) 11.0, Processor Power Delivery Design Guidelines – For Desktop LGA775 Socket, November 2006
This document defines the power delivery feature set necessary to support Intel processors’ Vcc power delivery requirements for desktop computer systems using the LGA775 socket. This includes design recommendations for DC to DC regulators, which convert the input supply voltage to a processor consumable Vcc voltage along with specific feature set implementation such as thermal monitoring and dynamic voltage identification.
Hardware solutions for the Vcc regulator are dependent upon the processors to be supported by a specific motherboard. Vcc regulator design on a specific board must meet the specifications of all processors supported by that board.
The voltage regulator configuration for a given processor is defined in that processor’s datasheet. In some instances, this data is not published and the proper mapping of processor to VRD configuration can be found from an authorized Intel representative. The voltage regulator-down designation of this document refers to a regulator with all components mounted directly on the motherboard for intent of supporting a single processor. For the corresponding documentation detailing voltage regulator modules (VRM) or a multiple-processor VRD, please refer to the VRM 10, EVRD 10 and EVRD 11 design guidelines documents.
