IR3522 DATA SHEET XPHASE3TM DDR & VTT CONTROL IC DESCRIPTION The IR3522 Control IC combined with IR3506 xPHASE3TM Phase ICs implements a full featured DDR3 power solution. The IR3522 provides control functions for both the VTT (single phase) and VDDR (multiphase) power rails which can interfaces with any number of IR3506 ICs each driving and monitoring TM a single phase to power any number of DDR3 DIMMs. The xPHASE3 architecture delivers a power supply that is smaller, more flexible, and easier to design while providing higher efficiency than conventional approaches.
