The IR3506 Phase IC combined with IR3522 xPHASE3 Control ICs implements a full featured DDR3 power solution. The IR3522 provides control functions for both the VDDR and VTT power rails and interfaces with any number of IR3506 Phase ICs each driving and monitoring a single phase to power any number of DDR3 TM DIMMs. The xPHASE3 architecture delivers a power s.
