Multi-Output Controller with Integrated MOSFET Drivers for AMD SVI Capable  
Mobile CPUs  
The ISL6265A is a multi-output controller with embedded  
gate drivers. A single-phase controller powers the  
Northbridge (VDDNB) portion of the CPU. The two  
Features  
• Core Configuration Flexibility  
- Dual Plane, Single-Phase Controllers  
- Uniplane, Two-Phase Controller  
remaining controller channels can be configured for  
two-phase or individual single-phase outputs. For uniplane  
CPU applications, the ISL6265A is configured as a  
two-phase buck converter. This allows the controller to  
interleave channels to effectively double the output voltage  
ripple frequency, and thereby reduce output voltage ripple  
amplitude with fewer components, lower component cost,  
reduced power dissipation, and smaller area. For dual-plane  
processors, the ISL6265A can be configured as independent  
single-phase controllers powering VDD0 and VDD1.  
• Precision Voltage Regulators  
- 0.5% System Accuracy Over-temperature  
• Voltage Positioning with Adjustable Load Line and Offset  
• Internal Gate Drivers with 2A Driving Capability  
• Differential Remote CPU Die Voltage Sensing  
• Core Differential Current Sensing: DCR or Resistor  
• Northbridge Lossless rDS(ON) Current Sensing  
The heart of the ISL6265A is the patented R3 Technology™,  
Intersil’s Robust Ripple Regulator modulator. Compared with  
the traditional buck regulator, the R3 Technologyhas a  
faster transient response. This is due to the R3 modulator  
commanding variable switching frequency during a load  
transient.  
• Serial VID Interface  
- Two Wire Clock and Data Bus  
- Supports High-Speed I2C  
- 0.500V to 1.55V in 12.5mV Steps  
- Supports PSI_L Power-Saving Mode  
• Core Outputs Feature Phase Shedding with PSI_L  
• Adjustable Output-Voltage Offset  
The Serial VID Interface (SVI) allows dynamic adjustment of  
the Core and Northbridge output voltages independently and  
in combination from 0.500V to 1.55V. Core and Northbridge  
output voltages achieve a 0.5% system accuracy  
over-temperature.  
• Digital Soft-Start of all Outputs  
• User Programmable Switching Frequency  
• Static and Dynamic Current Sharing (Uniplane Core)  
• Overvoltage, Undervoltage, and Overcurrent Protection  
• Pb-Free (RoHS compliant)  
A unity-gain differential amplifier is provided for remote CPU  
die sensing. This allows the voltage on the CPU die to be  
accurately regulated per AMD mobile CPU specifications.  
Core output current sensing is realized using lossless  
inductor DCR sensing. All outputs feature overcurrent,  
overvoltage and undervoltage protection.

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
