IR3082PbF
XPHASE TM AMD OPTERON TM /ATHLON 64 TM CONTROL IC
DESCRIPTION
The IR3082PbF Control IC combined with an IR XPhase TM Phase IC provides a full featured and flexible
way to implement a complete Opteron or Athlon64 power solution. The “Control” IC provides overall
system control and interfaces with any number of “Phase ICs” which each drive and monitor a single
phase of a multiphase converter. With simple 5 bit voltage programming and a few external components,
the IR3082PbF is also well suited for general purpose multiphase applications. The XPhase TM architecture
results in a power supply that is smaller, less expensive, and easier to design while providing higher
efficiency than conventional approaches.
