功能

  • Constant on-time controller for fast dynamic response on VDDQ
  • Programmable VDDQ range: 1.5 V to 3 V
  • 1% internal reference (2% system accuracy)
  • Resistor programmable on time for VDDQ
  • VCCA/VDDP range = 4.5 V to 5.5 V
  • VBAT range = 2.5 V to 25 V
  • VDDQ DC current sense using low-side RDS(ON) sensing or external RSENSE in series with low-side FET
  • Cycle-by-cycle current limit for VDDQ
  • Digital soft start for VDDQ
  • Combined EN and PSAVE pin for VDDQ
  • Over-voltage/under-voltage fault protection for both outputs and PGD output (VDDQ only)
  • Separate VCCA and VDDP supplies
  • VTT/REF range = 0.75 V – 1.5 V
  • VTT source/sink 3 A peak
  • Internal resistor divider for VTT/REF
  • VTT is high impedance in S3
  • VDDQ, VTT, and REF are actively discharged in S4/S5
  • 24-pin MLPQ (4 x 4mm) Lead-free package, fully
    WEEE and RoHS compliant
