ACPI Regulator/Controller for Dual  
Channel DDR Memory Systems  
Features  
• Generates 3 Regulated Voltages  
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  
- Synchronous Buck PWM Controller with Standby LDO  
- 3A Integrated Sink/Source Linear Regulator with  
Accurate VDDQ/2 Divider Reference.  
and integrated LDO to supply V  
with high current during  
DDQ  
- Glitch-free Transitions During State Changes  
- LDO Regulator for 1.5V Video and Core voltage  
S0/S1 states and standby current during S3 state. During  
S0/S1 state, a fully integrated sink-source regulator  
generates an accurate (V  
/2) high current V voltage

without the need for a negative supply. A buffered version of  
the V /2 reference is provided as V . An LDO

controller is also integrated for AGP core voltage regulation.  
• PWM Controller Drives Low Cost N-Channel MOSFETs  
• 250kHz Constant Frequency Operation  
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.  
• Tight Output Voltage Regulation  
- All Outputs: ±2% Over-Temperature  
• 5V or 3.3V Down Conversion  
• Fully-Adjustable Outputs with Wide Voltage Range: Down  
to 0.8V supports DDR and DDR2 Specifications  
• Simple Single-Loop Voltage-Mode PWM Control Design  
• Fast PWM Converter Transient Response  
• Under and Overvoltage Monitoring on All Outputs  
• OCP on the Switching Regulator  
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.  
• Integrated Thermal Shutdown Protection  
• QFN Package Option  
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

Each output is monitored for under and overvoltage events.  
The switching regulator has overcurrent protection. Thermal  
shutdown is integrated.

NOTE: These Intersil Pb-free plastic packaged products employ special  
Pb-free material sets; molding compounds/die attach materials and 100%  
matte tin plate PLUS ANNEAL - e3 termination finish, which is RoHS  
compliant and compatible with both SnPb and Pb-free soldering  
operations. Intersil Pb-free products are MSL classified at Pb-free peak  
reflow temperatures that meet or exceed the Pb-free requirements of  
IPC/JEDEC J STD-020.  
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
