PENTIUM® PROCESSOR P55C  
VOLTAGE REGULATOR MODULE

DESCRIPTION:  
FEATURES:  
The MP54C/MP55C series of power modules are low  
noise (no EMI), economical linear DC:DC converters  
with an integral connector conforming to Intel Corpora-  
tion’s Voltage Regulator Module specification for the  
Pentium® Processor.  
·
·
·
·
·
·
Integral VRM header connector  
Input voltage 5V ± 5%  
2.8 ± 0.1V output for CPU core power  
3.3V passes through the I/O power plane  
Maximum output current 6A  
Input power voltage:  
5V ± 5% for MP55C-5 or  
3.3V for MP55C-3.3  
Low noise, no EMI  
Outstanding features include internal current limiting  
and thermal shutdown, providing full device protection  
against load faults and thermal overstress. The MP55C  
is designed to power split voltage plane microproces-  
sors requiring 3.3V VI/O and 2.xV VCORE. The VI/O is al-  
ways supplied directly from a 3.3V input; either the  
main system power supply or a low dropout regulator  
on the motherboard. The CPU core can be supplied  
either from the 3.3V main supply to reduce heat dissi-  
pation (MP55C-3.3) or the 5V main power supply  
(MP55C-5). The MP55C-3.3 still requires a few mA of  
5V power for control circuitry. The MP55C-3.3 will not  
be available for CPU core voltages higher than 2.8V.  
Please contact Semtech for availability.
