IR3084U
XPHASE TM VR10, VR11 & OPTERON/ATHLON64 CONTROL IC
DESCRIPTION
The IR3084U Control IC combined with an IR XPhase
TM
Phase IC provides a full featured and flexible
monitor a single phase of a multiphase converter. The X Phase
architecture results in a power supply
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
TM
that is smaller, less expensive, and easier to design while providing higher efficiency than conventional
approaches.
The IR3084U is based on the IR3084 VR10 Control IC, but incorporates the following modifications;

?
Supports VR11 7-bit VID, VR10 7-bit extended VID, and Opteron/Athlon64 5-bit VID codes
Supports both VR11 and legacy Opteron/Athlon64 start-up sequences
VID Select pin sets the DAC to VR10, VR11, or Opteron/Athlon64
INTL_MD output pin indicates which DAC is selected – Intel or AMD
VOSENS? float detection protects the CPU in the event that the VOSENS? trace is broken
Enable Input Thresholds set by VID Select pin to either VR10, VR11 or Opteron/Athlon64
VID Input Thresholds set by VID Select pin to either 0.6V (VR10/VR11) or 1.24V (AMD)
No-Load Setpoint Current changes polarity based on VID Select to accommodate VR10, VR11
(negative offset from DAC) or Opteron/Athlon64 (positive offset from DAC).
