SC2615
Complete DDR Power Solution
Applications
DDR power solution for Intel
R
motherboard
applications
High speed data line termination
Graphic cards
Disk drives
Revision 2, April 2003
Typical Application Circuit
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 Intel
R
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.
In addition to these two blocks, an Internal LDO provides
VDDQ power during S3, capable of sourcing
650 mA
.
The SC2615 uses Intel
R
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.
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.
Single chip solution adheres to ACPI sleep state
requirements using BF_CUT
