Description
GND (Pin 1)
Signal ground for the IC.LGATE1, LGATE2 (Pin 2, 27)
These are outputs of the lower MOSFET drivers.PGND1, PGND2 (Pin 3, 26)
These pins provide the return connection for lower gate drivers.These pins are connected to sources of the lower MOSFETs of their respective converters.DDR (Pin 13)
This pin, when high, transforms dual channel chip into complete DDR memory solution.The OCSET2 pin becomes an input to provide the required tracking function.The channel synchronization is ch
Features
- Provides regulated output voltage in the range of 0.9V-5.5V - High efficiency over wide load range - Synchronous buck converter with hysteretic operation at light load - Inhibit Hysteretic mode on one, or both channels.
- Complete DDR memory power solution - VTT tracks VDDQ/2 - VDDQ/2 buffered reference output.
- No current-sense resistor required - Uses MOSFET RDS(ON) - Optional current-sense resistor for precision Over-Current.
- Under-voltage lock-out on VCC pin.
