IR3500A
DATA SHEET
XPHASE3 TM VR11.0 & AMD PVID CONTROL IC
DESCRIPTION
The IR3500A Control IC combined with an xPHASE3
TM
Phase IC provides a full featured and flexible way
multiphase converter. The X Phase3
architecture implements a power supply that is smaller, less
to implement a complete VR11.0 or AMD PVID 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
TM
expensive, and easier to design while providing higher efficiency than conventional approaches.
