... POWER MANAGEMENT Description The SC2516 is a fully integrated, Three-in-One DDR Con- troller 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 regu- lator supplies the termination voltage with 1.8A(min) Source/Sink capability ...

... VDDQ Power Section SC2516 architecture eliminates the need for the Back- Feed Cut MOSFET, since the VDDQ is always supplied from the same input voltage bus (5V dual). The SC2516 is capable of driving a 4000pf capacitor in 25ns (typical, top gate). This drive capability allows 15-20A DC load on the VDDQ supply from the 5V main input rail ...
