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.

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.
