Overview
DATASHEET ISL6532B ACPI Regulator/Controller for Dual Channel DDR Memory Systems FN9120 Rev 3.
00 Jul 2004 VDDQ VTTSNS P5VSBY VREF_OUT VREF_IN The ISL6532B 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 Run mode, 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.
The switching PWM controller drives two N-Channel MOSFETs in a synchronous-rectified buck converter topology.
The synchronous buck converter uses voltagemode control with fast transient response.
Both the switching regulator and integrated standby LDO provide a maximum static regulation tolerance of 2% over line, load, and temperature ranges.
The output is...
