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 a.

• I2C interface programs 1.025V< VREF1<1.612V, the VDD output voltage reference I2C also programs the VTT tracking ratio ± 25 %, and provides digital ON/OFF control Four different I2C addresses are selectible using 2 ADDR pins Four different VREF1 voltages are selectible using 2 VID pins if I2C communication is not available VTT tracking defaults to ½ the VDD Remote Sense Amp output voltage Power Good output driven by an external bias input VDD to VTT overvoltage protection Soft-Stop turn-off to ensure VDDR and Vtt tracking Fault activated Crowbar pin to drive externa.
