Description	XPHASE3 AMD SVID CONTROLLER
Datasheet	IR3521 Datasheet

The IR3521 Control IC combined with an xPHASE3TM 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.

IR3521 DATA SHEET XPHASE3TM AMD SVID CONTROL IC.

2 converter outputs for the AMD processor VDD core and VDDNB auxiliary planes.
Supports High Speed (HS) I2C Serial communications.
PSI_L serial commands are communicated to a programmable number of phase ICs.
0.5% overall system set point accuracy.
High speed error amplifiers with wide bandwidth of 20MHz and fast slew rate of 10V/us.
Remote sense amplifiers provide differential sensing and require less than 50uA bias current.
Programmable Dynamic VID Slew Rate.
