POWER MANAGEMENT
Description
The SC2596 is an integrated linear DDR termination
device, which provides a complete solution for DDR
termination regulator designs; while meeting the JEDEC
requirements of SSTL-2 and SSTL-18 specifications for
DDR-SDRAM termination.
The SC2596 regulates up to +/- 2.5A for DDR-I and +/-
1.5A for DDR-II application requirements.
V is regulated to track the V voltage over the entire
TT
REF
current range with shoot through protection.
SC2596
Low Voltage Integrated DDR
Termination Regulator
Features
 Sourcing or sinking 2.5A for DDR-I
 Sourcing or sinking 1.5A for DDR-II
Â
Â
AVCC undervoltage lockout
Reference output
 Minimum number of external components
 Accurate internal voltage divider
 Disable function, puts device into sleep mode
 Thermal shutdown
 Over current protection
 Available in SOIC-8 EDP package
 WEEE and RoHS compliant
A VSENSE pin is incorporated to provide excellent load
regulation, along with a buffered reference voltage for
internal use.
The SC2596 also features a disable function which is to
tri-state the output during Suspend To Ram (STR) states
by pulling the EN pin low.
Applications
 DDR-I and DDR-II memory termination
 SSTL-2 and SSTL-3 termination
 HSTL termination
 PC motherboards
 Graphics boards
 Disk drives
 CD-ROM drives
