IntelŪ PentiumŪ 4 Processor VR-Down Design Guidelines
This document defines DC-to-DC converters to meet the power requirements of computer systems using Intel microprocessors. Requirements will vary according to the needs of different computer systems and processors that a specific voltage regulator (VR) is expected to support. The ?VR? designation in this document refers to an embedded voltage regulator on a system board. Please refer to the VRM 9.1 Design Guidelines for Voltage Regulator Module design guidelines. The major differences between this document and the VRM 9.1 guidelines are: This document defines solutions for systems with a single processor; it does not include current-sharing requirements, which are applicable to powering multiple processors. Voltages are specified at the processor socket instead of the VRM connector.
This document is specifically intended to meet the needs of systems based on the IntelŪ PentiumŪ 4 processor in the 423-pin package, Intel Pentium 4 processor in the 478-pin package, and Pentium 4 processor with 512-KB L2 cache on 0.13 micron process. Related Documents
