ISL6548 NOT RECOMMENDED FOR NEW DESIGNS NO RECOMMENDED REPLACEMENT contact our Technical Support Center at 1-888-INTERSIL or www.intersil.com/tsc ACPI Regulator/Controller for Dual Channel DDR Memory Systems DATASHEET FN9188 Rev 2.00 January 3, 2006 VDDQ DDR_VTTSNS DRIVE2_U FB2 VIDPGD DRIVE2_L VREF_IN The ISL6548 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.
