IR3084U - International Rectifier

IR3084U OPTERON/ATHLON64 CONTROL IC

The IR3084U Control IC combined with an IR XPhaseTM Phase IC provides a full featured and flexible way to implement a complete VR10, VR11, 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. The XPhaseTM archi.
