Description and Introduction

Multiphase PWM Regulator for AMD Fusion Mobile CPUs The ISL6267HRZ is a dual-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:** 4.5V to 24V  
- **Output Voltage Range:** Adjustable from 0.3V to 5.5V  
- **Switching Frequency:** Adjustable from 200kHz to 1.5MHz  
- **Number of Phases:** Dual-phase (2-phase)  
- **Package:** 40-Lead QFN (6x6mm)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Control Method:** Voltage-mode PWM  

### **Descriptions:**  
The ISL6267HRZ is a high-performance, dual-phase synchronous buck PWM controller designed for precision voltage regulation in applications such as notebook CPUs, GPUs, and other point-of-load (POL) power supplies. It supports adaptive voltage positioning (AVP) and provides accurate current balancing between phases.  

### **Features:**  
- **Dual-Phase Operation:** Enhances efficiency and reduces input/output ripple.  
- **Adaptive Voltage Positioning (AVP):** Optimizes transient response.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency or component size.  
- **Precision Voltage Regulation:** ±0.5% system accuracy over temperature.  
- **Current Balancing:** Ensures equal load sharing between phases.  
- **Overcurrent Protection (OCP):** Prevents damage during fault conditions.  
- **Power Good (PGOOD) Indicator:** Monitors output voltage status.  
- **Differential Remote Sensing:** Compensates for PCB trace resistance.
