| PENTIUM PRO PROCESSOR VOLTAGE REGULATOR MODULE November 3, 1997 (R) MP60-E TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The MP60 series of power modules are economical switching DC/DC converters with an integral connector conforming to Intel Corporation's Voltage Regulator Module specification for the Pentium(R) Pro Processor. The modules have additional monitoring functions for Power Good Signal, Output Enable and Upgrade Present. The output voltage can be set between 2.1V and 3.5V by means of a four bit voltage identification code, to support current and future versions of the Pentium Pro and OverDrive(R) processor variants. To power Pentium II processors (VRM 8.1) use MP60-F or MP60-G. FEATURES * Integral 40-pin header connector * Programmable output voltage to suit processor * * * (by VID code); adjustable from 2.1 to 3.5V Maximum output current 15A Efficiency >80% at full load Designed to specifications for Intel Pentium(R) Pro Processor voltage regulator module APPLICATIONS * Intel Pentium(R) Pro Power Supply * Deshutes Memory Power Supply (2.5V) ORDERING INFORMATION DEVICE MP60-E MP60-E-HC IOUT 13A 15A VOUT (volts) 4 Bit Programmable 4 Bit Programmable ELECTRICAL CHARACTERISTICS Conditions: VO = 3.1V, VIN = 4.75 - 5.25V, IO = 10A, unless otherwise stated.

The PWRGD signal will change to the proper state within 5ms of the output coming into or going out of specification. Output Enable: A low state disables the output voltage. When disabled, the PWRGD signal shall be in the low state. Upgrade Present: Used to indicate the presence of an upgrade processor. Typical state is high (standard processor in system). When in the low or ground state (OverDriveTM processor in system) the output voltage shall be disabled unless the converter can supply to an OverDrive processor's specifications. When disabled, the PWRGD output will be in the low state. Voltage Identification: The module will accept four open collector signals, used to indicate the voltage required by the processor, as defined by Intel Main power input for regulation. Must also be connected (input for control circuits only) OUTEN UP# VID(0:3) 5V in 12V in Pentium and OverDrive are registered trademarks of Intel Corporation (c) 1997 SEMTECH CORP. 652 MITCHELL ROAD NEWBURY PARK CA 91320 PENTIUM PRO PROCESSOR VOLTAGE REGULATOR MODULE November 3, 1997 VOLTAGE IDENTIFICATION CODE VID3 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0 Pentium Pro Pins VID2 VID1 1 1 1 1 1 0 1 0 0 1 0 1 0 0 0 0 1 1 1 1 1 0 1 0 0 1 0 1 0 0 0 0 VID0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 VCCP (VDC) 2.0 (no CPU) 2.1 2.2 2.3 2.4 2.5 2.6 2.7 2.8 2.9 3.0 3.1 3.2 3.3 3.4 3.5 (R) MP60-E 0 = processor pin connected to VSS, 1 = open MECHANICAL DIMENSIONS Component size and location for illustration only Dimension A B C D E F G H J K mm 79.7 43.2 24.4 57.4 8.13 10.67 + 0.13 3.81 6.50 21.6 2.5 inch 3.14 1.70 0.96 2.26 0.32 0.42 + 0.005 0.15 0.26 0.85 0.10 Max Max Max Typ Typ Typ Typ Min Max Min Pentium and OverDrive are registered trademarks of Intel Corporation (c) 1997 SEMTECH CORP. 652 MITCHELL ROAD NEWBURY PARK CA 91320 |
