MP55C

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.
