VOLTAGE REGULATOR MODULE FOR INTEL ADVANCED PROCESSORS PRELIMINARY - November 3, 1997 MP60G TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The MP60G series of power modules are highly efficient synchronous switching DC/DC converters with an integral connector conforming to Intel Corporation’s Voltage Regulator Module specification (VRM 8.1 DC-DC Converter Specification). The modules have additional monitoring functions for Power Good Signal, Output Enable and optional Over Voltage Protection. A five bit voltage identification code (VID) programs the output voltage between 1.8V and 3.5V to support existing and future versions of the Pentium® II processor. The MP60G is available in several options to provide superior cost/performance tradeoff. The MP60G-5N, -5P and -NH modules convert 5V to the programmed VID output. The N designation signifies no Over Voltage Protection (OVP) while the P represents OVP. The NH module does not provide OVP and does not have heat sinks. The MP60G-12XX modules are intended for 12V server applications. Again, the N and P designations denote the OVP option. The MP60G-12A will work from either 5V or 12V input on the 5Vin pins (Pins 1A, 2A, 3A, 1B and 2B).

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. Microprocessor core voltage programmed with VID inputs System Ground 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.
