DESCRIPTION:
The MP54C/MP55C series of power modules are low
noise (no EMI), economical 25W (nominal) linear
DC:DC converters with an integral connector con-
forming to Intel Corporation鈥檚 Voltage Regulator Mod-
ule specification for the Pentium
廬
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鈥檚 datasheet, MP55C.
