PENTIUM^®PROCESSOR P55C

VOLTAGE REGULATOR MODULE

MP55C

October 27, 1997

TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com

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 V_I/Oand 2.xV V_CORE. The V_I/Ois 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.
