IR3521
DATA SHEET
XPHASE3 TM AMD SVID CONTROL IC
DESCRIPTION
The IR3521 Control IC combined with an xPHASE3 TM Phase IC provides a full featured and flexible way to
implement a complete AMD SVID power solution. It provides outputs for both the VDD core and VDDNB
auxiliary planes required by the CPU. The IR3521 provides overall system control and interfaces with any
number of Phase ICs each driving and monitoring a single phase. The xPHASE3 TM architecture results in a
power supply that is smaller, less expensive, and easier to design while providing higher efficiency than
conventional approaches.
