ACPI Regulator/Controller for  
Features  
Dual Channel DDR Memory Systems  
• Generates 4 Regulated Voltages  
- Synchronous Buck PWM Controller for DDR V  
- 3A Integrated Sink/Source Linear Regulator with  
Accurate VDDQ/2 Divider Reference for DDR V  
- LDO Regulator for GMCH Core  
- Sink/Source LDO Regulator for CPU/GMCH V  
Termination  
The ISL6548 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  
DDQ  
TT  
supply V  
during S0/S1 and S3 states. During S0/S1  
DDQ  
state, a fully integrated sink-source regulator generates an  
accurate (V /2) high current V voltage without the  
TT  
DDQ  
TT  
need for a negative supply. Two LDO controllers are also  
integrated for the GMCH core voltage regulation and for the  
GMCH/CPU V termination voltage regulation.  
• ACPI compliant sleep state control  
• Glitch-free Transitions During State Changes  
TT  
• PWM Controller Drives Low Cost N-Channel MOSFETs  
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. The switching  
regulator provides 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.  
• 250kHz Constant Frequency Operation  
• Tight Output Voltage Regulation  
- All Outputs: ±2% Over Temperature  
• 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  
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 VIDPGD signal  
indicates that the GMCH/CPU V termination voltage is  
TT  
within spec and operational.  
• Integrated Thermal Shutdown Protection  
• Pb-Free Available (RoHS Compliant)  
Each output is monitored for undervoltage events. The  
switching regulator also has overvoltage and overcurrent  
protection. Thermal shutdown is integrated.

NOTE: Intersil Pb-free products employ special Pb-free material sets; molding  
compounds/die attach materials and 100% matte tin plate termination finish, which are  
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.
