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).

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 16A

• Efficiency >85% at full load

• Fast transient response

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 shall
be in the low state.
