ORDERING INFORMATION

DESCRIPTION

The MP60 series of power modules are economical switching DC/DC converters with an integral connec- tor conforming to Intel Corporation’s Voltage Regula- tor Module specification for the Pentium ® Pro Proces- sor. The modules have additional monitoring func- tions for Power Good Signal, Output Enable and Up- grade 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 ® 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 ® Pro Processor voltage regulator module DEVICE IOUT V OUT (volts) MP60-E 13A 4 Bit Programmable MP60-E-HC 15A 4 Bit Programmable

ELECTRICAL CHARACTERISTICS

Conditions: V O = 3.1V, V IN = 4.75 - 5.25V, I O = 10A, unless otherwise stated.

PENTIUM ® PRO PROCESSOR VOLTAGE REGULATOR MODULE November 3, 1997 VOLTAGE REGULATOR MODULE CONNECTOR PIN REFERENCE Pin Name Pin Function PWRGD Power Good: When the output voltage is not within specifications (nominal or selected voltage + 7%) this signal will be in the low state. The PWRGD signal will change to the proper state within 5ms of the output coming into or going out of specification. OUTEN Output Enable: A low state disables the output voltage. When disabled, the PWRGD signal shall be in the low state. UP# 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 (OverDrive™ 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. VID(0:3) Voltage Identification: The module will accept four open collector signals, used to indicate the voltage required by the processor, as defined by Intel 5V in Main power input for regulation. 12V in Must also be connected (input for control circuits only) INPUT AND OUTPUT CONNECTIONS Pin No. Row A Row B Pin No. 1 5V in 5V in 1 2 5V in 5V in 2 3 5V in 5V in 3 4 12V in 12V in 4
