Description and Introduction

Two-Phase Buck PWM Controller with Integrated MOSFET Drivers for VRM9, VRM10, and AMD Hammer Applications The ISL6568CR is a multi-phase PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Input Voltage Range:** 5V to 12V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Number of Phases:** 2, 3, or 4-phase operation  
- **Switching Frequency:** Adjustable from 50kHz to 1MHz per phase  
- **Current Sensing:** Lossless inductor DCR sensing or precision resistor sensing  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-lead QFN (Quad Flat No-Lead)  

### **Descriptions:**  
- Designed for high-efficiency, multi-phase DC-DC conversion in VRM (Voltage Regulator Module) applications.  
- Supports Intel VRD (Voltage Regulator Down) specifications for CPUs and GPUs.  
- Provides accurate voltage regulation and dynamic phase management for improved efficiency.  

### **Features:**  
- **Adaptive Phase Control:** Dynamically adjusts the number of active phases for optimal efficiency.  
- **Precision Voltage Regulation:** ±0.5% system accuracy over temperature.  
- **Overcurrent Protection (OCP):** Monitors and limits output current.  
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage.  
- **Programmable Soft-Start:** Prevents inrush current during startup.  
- **Differential Remote Voltage Sensing:** Ensures accurate voltage regulation at the load.  
- **Power-Good Output:** Indicates stable output voltage.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics, refer to the official datasheet.
