Product is not recommended for new design.
功能
- 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
- Separate VCCA and VDDP supplies
- VTT/REF range = 0.75V – 1.5V
