General 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 xPHASE3TM Phase ICs each driving and monitoring a single phase.

Output 1 includes a 3 bit VR11.x VID, 1.1V boot voltage and droop to implement the CPU VTT rail which is typically 1 phase.
