The SC2616 is a fully integrated DDR power solution providing 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 S3 and S5 motherboard signals.
