DATASHEET ISL6548A ACPI Regulator/Controller for Dual Channel DDR Memory Systems FN9189 Rev 2.00 January 3, 2006 The ISL6548A 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 second PWM controller, which requires external MOSFET drivers, is available for regulation of the GMCH Core voltage. A sink/source LDO controller is also integrated for the CPU/GMCH VTT termination voltage regulation. Another LDO is available for the ICH7 voltage.
