KLAMATH PROCESSOR VOLTAGE REGULATOR MODULE October 27, 1997 MP60-F TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION: The MP60 series of power modules are economical 49W (nominal) switching DC:DC converters with an integral connector designed to Intel Corporation’s Voltage 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 Processor voltage regulator module Fast transient response APPLICATIONS: • Intel Klamath Power Supply ORDERING INFORMATION: DEVICE VOUT (volts) MP60-F 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 will 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 five open collector signals, used to indicate the voltage required by the processor, as defined by Intel Main power input for regulation.
