SC2616  
Complete DDR Power Solution  
POWER MANAGEMENT  
Description  
Features  
The SC2616 is a fully integrated DDR power solution pro-  
viding power for the VDDQ and the VTT rails. The SC2616  
also completely adheres to the ACPI sleep state power  
requirements. A synchronous buck controller provides  
the high current of the VDDQ at high efficiency, while a  
linear sink/source regulator provides the termination  
voltage with 2 Amp Source/Sink capability. This approach  
makes the best trade-off between cost and perfor-  
mance. Additional logic and UVLOs complete the func-  
tionality of this single chip DDR power solution in compli-  
ance with S3 and S5 motherboard signals.  
‹ High efficiency (90%) switcher for VDDQ supplies  
20 Amps  
‹ High current gate drives  
‹ Single chip solution complies fully with ACPI power  
sequencing specifications  
‹ Internal S3 state LDO supplies high standby  
VDDQ current (0.65Amp Min.)  
‹ ACPI sleep state controlled  
‹ 2 Amp VTT source/sink capability  
‹ UVLO on 5V and 12V  
‹ Independent thermal shutdown for VDDQ and VTT  
‹ Fast transient response  
The SC2616 is capable of sourcing up to 20A at the  
switcher output, and 2A source/sink at the VTT output.  
The MLP package provides excellent thermal impedance  
while keeping small footprint. VDDQ current limit as well  
as 3 independent thermal shutdown circuits assure safe  
operation under all fault conditions.  
‹ 18 pin MLP package  
Applications  
‹ Power solution for DDR memory per ACPI  
motherboard specification  
‹ High speed data line termination  
‹ Memory cards
