POWER MANAGEMENT
Description
The SC2595 is an integrated linear DDR termination
device, which provides a complete solution for DDR
termination designs; while meeting the JEDEC require-
ments of SSTL-2 specifications for DDR-SDRAM termi-
nation.
The SC2595 can source and sink 1.5A current at the
output VTT while maintaining excellent load regulation.
VTT is designed to track the VREF voltage with a tight
tolerance over the entire current range while preventing
shoot through on the output stage.
A VSENSE pin is incorporated to provide excellent load
regulation, along with a buffered reference voltage.
