Product Summary

The IR3522MTRPBF Control IC combined with IR3506 xPHASE3 Phase ICs implements a full featured DDR3 power solution. The IR3522MTRPBF 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 a single phase to power any number of DDR3 DIMMs. The IR3522MTRPBF architecture delivers a power supply that is smaller, more flexible, and easier to design while providing higher efficiency than conventional approaches.

Parametrics

IR3522MTRPBF absolute maximum ratings: (1)Operating Junction Temperature: 0 to 150oC; (2)Storage Temperature Range: -65oC to 150oC; (3)ESD Rating: HBM Class 1C JEDEC Standard; (4)Reflow Temperature: 260°C; (5)Bias Current: -5 to 5 uA; (6)SDA Low Voltage I(SDA)= 3mA: 20 to 300 mV; (7)SDA Output Fall Time: 250 ns.

Features

IR3522MTRPBF features: (1)I2C interface programs 1.025V< VREF1<1.612V, the VDD output voltage reference; (2)I2C also programs the VTT tracking ratio ± 25 %, and provides digital ON/OFF control; (3)Four different I2C addresses are selectible using 2 ADDR pins; (4)Four different VREF1 voltages are selectible using 2 VID pins if I2C communication is not available; (5)VTT tracking defaults to ½ the VDD Remote Sense Amp output voltage; (6)Power Good output driven by an external bias input; (7)VDD to VTT overvoltage protection; (8)Remote sense amplifiers provide differential sensing and requires less than 50uA bias current; (9)Pin programmable per phase switching frequency of 250kHz to 1.5MHz; (10)Complete protection including over-current, over-voltage, open remote sense, and open control.
