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 (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.

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
