ACPI Regulator/Controller for Dual
Channel DDR Memory Systems
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 V DDQ 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 (V DDQ /2) high current V TT voltage
without the need for a negative supply. A buffered version of
the V DDQ /2 reference is provided as V REF . An LDO
controller is also integrated for AGP core voltage regulation.
The switching PWM controller drives two N-Channel
MOSFETs in a synchronous-rectified buck converter
topology. The synchronous buck converter uses voltage-
mode control with fast transient response. Both the switching
regulator and standby LDO provide a maximum static
regulation tolerance of ± 2% over line, load, and temperature
ranges. The output is user-adjustable by means of external
resistors down to 0.8V.
Switching memory core output between the PWM regulator
and the standby LDO during state transitions is
accomplished smoothly via the internal ACPI control
circuitry. The NCH signal provides synchronized switching of
a backfeed blocking switch during the transitions eliminating
the need to route 5V Dual to the memory supply.
An integrated soft-start feature brings all outputs into
regulation in a controlled manner when returning to S0/S1
state from any sleep state. During S0 the PGOOD signal
indicates V TT is within spec and operational.
Each output is monitored for under and overvoltage events.
The switching regulator has overcurrent protection. Thermal
shutdown is integrated.
