DESCRIPTION:
MP54C/MP55C series power modules noise EMI), economical (nominal) linear DC:DC converters with integral connector conforming Intel Corporation's Voltage Regulator Module specification Pentium® Processor. Outstanding features include internal current limiting thermal shutdown, providing full device protection against load faults thermal overstress. MP54C series designed supply power Pentium Processor P54C P54CS associated chip sets. With tightly controlled output voltage, nominally 3.525V, MP54C meets requirements powering specification processors. MP54C-5E reduced cost version offering maximum current P55C processors, please Semtech's datasheet, MP55C.
