ACPI Regulator/Controller for Dual Channel DDR Memory Systems
DATASHEET
FN9099 Rev 6.00 Sep 12, 2013
The ISL6532A 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 and integrated LDO to supply VDDQ with high current during S0/S1 states and standby current during S3 state. 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.
