DESCRIPTION:
The MP60 series of power modules are economical
49W (nominal) switching DC:DC converters with an
integral connector designed to Intel Corporation's Volt-
age Regulator Module specification for the Klamath
Processor. The module has additional monitoring
functions for Power Good Signal, Output Enable and
Upgrade Present.
The output voltage can be set between 1.8V and 3.5V
by means of a five bit voltage identification code, to
support current and future versions of the Pentium
Pro, Klamath and OverDrive
processor variants.
To power Pentium
Pro processors (VRM 8.0) use
MP60-E.
FEATURES:
Integral 40-pin header connector
Programmable output voltage to suit processor (by
VID code); adjustable from 1.8 to 3.5V
Maximum output current 14A
Efficiency >80% at full load
Designed to specifications for Intel Klamath Pro-
cessor voltage regulator module
Fast transient response

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 will 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 (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.
VID(0:4)
Voltage Identification: The module will accept five open collector signals, used to indicate the
voltage required by the processor, as defined by Intel
