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
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
