Features

  • Constant on-time controller for fast dynamic response on VDDQ
  • DDR1/DDR2/DDR3 compatible
  • VDDQ = fi xed 1.8V or 2.5V, or adjustable from 1.5V to 3.0V
  • 1% internal reference (2% system accuracy)
  • Resistor programmable on-time for VDDQ
  • VCCA/VDDP range = 4.5V to 5.5V
  • VIN range = 2.5V to 25V
  • 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
  • Analog soft-start for VTT/REF
  • Smart over-voltage VDDQ protection against source-current loads
  • Combined EN and PSAVE pin for VDDQ
  • Over-voltage/under-voltage fault protection
  • Power good output
