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).

Pin Function
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.
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.
Must also be connected (input for control circuits only)
