DATASHEET ISL6537 ACPI Regulator/Controller for Dual Channel DDR Memory Systems FN9142 Rev 6.00 Jul 18, 2007 VDDQ DDR_VTTSNS DRIVE2 FB2 VIDPGD VREF_OUT VREF_IN The ISL6537 provides a complete ACPI compliant power solution for up to 4 DIMM dual channel DDR/DDR2 Memory systems. Included are both a synchronous buck controller to supply VDDQ during S0/S1 and S3 states. During S0/S1 state, a fully integrated sink-source regulator generates an accurate (VDDQ/2) high current VTT voltage without the need for a negative supply. A buffered version of the VDDQ/2 reference is provided as VREF. Two LDO controllers are also integrated for the GMCH core voltage regulation and for the GMCH and CPU VTT termination voltage regulation.
