SC2516
Description
The SC2516 is a fully integrated, Three-in-One DDR Controller supplying power to the VDDQ, VTT and GMCH rails. Two synchronous buck controller provide the VDDQ and GMCH at high efficiency, while an internal linear regulator supplies the termination voltage with 1.8A(min) Source/Sink capability. The SC2516 uses the Intel® defined Latched BF_Cut signal to ply with motherboard state transitions. The regulator uses the 5VDUAL rail to supply VDDQ under all motherboard states, via the VDDQ switcher. The GMCH regulator is slaved off the 5V main regulator, using a separate UVLO on that rail. Additional logic and supervisory circuitry plete the functionality of this single chip DDR power solution in pliance with ACPI requirements. thermal impedance while keeping small footprint. VDDQ short circuit protection along with VTT current limit as well as two independent thermal shutdown circuits assure safe operation under all fault conditions.
