SC2516MLTR Datasheet - Semtech Corporation

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.

FEATUREs
◆ Uses Latched BF_Cut from Intel Glue Chip to control regulators
◆ External VDDQ divider allows DDRI or DDRII Compatibility
◆ High efficiency VDDQ switcher
◆ External GMCH divider allows 1.5V or 1.25V programming
◆ High efficiency GMCH switcher supplies programmed output from the 5V or 3.3V rail
◆ Single chip solution complies fully with ACPI power sequencing specifications
◆ 1.8A (min) VTT Source/Sink capability
◆ High current 1Amp gate driver for VDDQ switcher
◆ Independent thermal shutdown for VTT
◆ Fast transient response
◆ Space saving 22-pin MLP package with copper thermal pad for heatsinking to PC Board

APPLICATIONs
◆ Power Solution for DDR memory per Intel motherboard specification
◆ High speed data line termination
