MP54C Datasheet | SEMTECH

ESCRIPTION: The MP54C/MP55C series of power modules are low noise (no EMI), economical 25W (nominal) 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 MP54C series is designed to supply power for the Pentium Processor P54C & P54CS and associated chip sets. With a tightly controlled output voltage, nominally 3.525V, the MP54C meets all requirements for powering VRE specification processors. The MP54C-5E is a reduced cost version offering a maximum current of 5A. For P55C processors, please see Semtech’s datasheet, MP55C.
