Product Description

**_Four-Phase Buck PWM Controller with _****_Integrated MOSFET Drivers for Intel VR10, _****_VR11, and AMD Applications_**
The ISL6312 four-phase PWM control IC provides a precision voltage regulation system for advanced
microprocessors. The integration of power MOSFET drivers into the controller IC marks a departure from the separate PWM controller and driver configuration of previous multiphase product families. By reducing the number of external parts, this integration is optimized for a cost and space saving power management solution.
**_Features_**
• Integrated Multiphase Power Conversion
\- 2- or 3-Phase Operation with Internal Drivers
\- 4-Phase Operation with External PWM Driver Signal
• Precision Core Voltage Regulation
\- Differential Remote Voltage Sensing
\- ±0.5% System Accuracy Over-Temperature
\- Adjustable Reference-Voltage Offset
• Optimal Transient Response
\- Active Pulse Positioning (APP) Modulation
\- Adaptive Phase Alignment (APA)
• Fully Differential, Continuous DCR Current Sensing
\- Accurate Load Line Programming
\- Precision Channel Current Balancing
• User Selectable Adaptive Dead Time Scheme
\- PHASE Detect or LGATE Detect for Application Flexibility
• Variable Gate Drive Bias: 5V to 12V
• Multi-Processor Compatible
\- Intel VR10 and VR11 Modes of Operation
\- AMD Mode of Operation
• Microprocessor Voltage Identification Inputs
\- 8-bit DAC
\- Selectable between Intel’s Extended VR10, VR11, AMD 5-bit, and AMD 6-bit DAC Tables
\- Dynamic VID Technology
• Overcurrent Protection
• Multi-Tiered Overvoltage Protection
• Digital Soft-Start
• Selectable Operation Frequency up to 1.5MHz Per Phase
• Pb-Free (RoHS Compliant)
