Semtech SC2615
Complete DDR Power Solution, Intel Reference Design
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 IntelR 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.
