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 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.

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 Intel^Rdefined 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 Intel^Rmotherboard

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.
