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 performance.

Additional logic and UVLOs complete the functionality of

this single chip DDR power solution in compliance with

SLP_S3 and SLP_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 (0.65 Amp Min.)

ACPI sleep state controlled

2 Amp VTT source/sink capability

UVLO on 5V and 12V

Indepent thermal shutdown for VDDQSTBY and VTT

Fast transient response

18 pin MLP package

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.
