Phase ICs each driving and monitoring a single phase. Output 1 includes a 3 bit VR11.x VID, 1.1V
xPHASE3
margining and supports any number of phases and DDR DIMM modules. The xPHASE3
architecture results in a

DATASHEET
XPHASE3 TM DUAL OUTPUT CONTROL IC
DESCRIPTION
The IR3523 Control IC provides a full featured and flexible way to implement a complete dual output DDR &
CPU VTT multiphase power solution for Intel VR11.1 motherboards. Each output interfaces with any number of
TM
boot voltage and droop to implement the CPU VTT rail which is typically 1 phase. Output 2 includes a 3 bit VID for
TM
power supply that is smaller, less expensive, and easier to design while providing higher efficiency than
conventional approaches.
