MP55C

PENTIUM PROCESSOR P55C VOLTAGE REGULATOR MODULE October 27, 1997 ® MP55C TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION: The MP54C/MP55C series of power modules are low noise (no EMI), economical linear DC:DC converters with an integral connector conforming to Intel Corporation’s Voltage Regulator Module specification for the Pentium® Processor. 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 microprocessors requiring 3.3V VI/O and 2.xV VCORE. The VI/O is always 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 dissipation (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. FEATURES: 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 ORDERING INFORMATION: DEVICE MP55C-5-2.8 MP55C-5-2.5 MP55C-3.3-2.8 MP55C-3.3-2.7 MP55C-3.3-2.5 Input (V) 5.0 5.0 3.3 3.3 3.3 Output (V...
