® PENTIUM PRO PROCESSOR VOLTAGE REGULATOR MODULE November 3, 1997 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® 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® 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 • • • APPLICATIONS • Intel Pentium® Pro Power Supply • Deshutes Memory Power Supply (2.5V) ORDERING INFORMATION DEVICE IOUT VOUT (volts) MP60-E 13A 4 Bit Programmable MP60-E-HC 15A 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 (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. 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.
