SC2615  
Complete DDR Power Solution  
POWER MANAGEMENT  
Description  
Features  
The SC2615 is a fully integrated, Three in One, Linear  
DDR power solution providing power for the VDDQ and  
the VTT rails. The SC2615 completely adheres to the  
ACPI sleep state power requirements per IntelR  
motherboard specifications. A linear regulator controller  
provides the high current of the VDDQ during S0, via an  
external Power MOSFET, while an internal 1.8A (min) sink/  
source regulator supplies the termination voltage.  
‹ Single chip solution adheres to ACPI sleep state  
requirements using BF_CUT  
‹ UVLO on 3.3V and 12V  
‹ Internal S3 state LDO for VDDQ supplies 650 mA  
‹ Dual thermal shutdown  
‹ Fast transient response  
‹ Internal VTT regulator Sinks and Sources 1.8A  
(Min)  
‹ Power good output  
‹ 18 pin MLP package  
In addition to these two blocks, an Internal LDO provides  
VDDQ power during S3, capable of sourcing 650 mA.  
The SC2615 uses IntelR defined Latched BF_CUT signal  
which is also used to drive the external Blocking MOSFET.  
Additional logic, two UVLOs and three thermal shutdown  
circuits assure reliability of this single chip DDR power  
solution. A Power Good Output indicates the rails are in  
regulation.  
Applications  
‹ DDR power solution for IntelR motherboard  
applications  
‹ High speed data line termination  
‹ Graphic cards  
‹ Disk drives  
A Soft Start/Enable pin assures proper startup and allows  
external shutdown control. The MLP package provides  
excellent thermal impedance while keeping a small  
footprint.
