Description and Introduction

Multi-Phase PWM Controller The ISL6244CRZ is a dual-phase, synchronous buck PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 25V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** Adjustable from 200kHz to 1MHz  
- **Maximum Duty Cycle:** 100%  
- **Number of Phases:** Dual-phase  
- **Current Balancing:** Precision current sharing between phases  
- **Efficiency:** High efficiency due to synchronous rectification  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-Lead QFN (5mm x 5mm)  

### **Descriptions:**
- The ISL6244CRZ is designed for high-performance voltage regulation in notebook computers, servers, and other power-sensitive applications.  
- It supports dual-phase operation, improving efficiency and thermal performance.  
- The controller includes adaptive voltage positioning (AVP) for transient response optimization.  
- It integrates MOSFET drivers and provides overcurrent, overvoltage, and undervoltage protection.  

### **Features:**
- **Dual-Phase Operation:** Enhances power delivery and reduces input/output capacitance requirements.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency or component size.  
- **Precision Voltage Regulation:** ±1% accuracy over line, load, and temperature variations.  
- **Adaptive Voltage Positioning (AVP):** Improves transient response and reduces output capacitance.  
- **Integrated MOSFET Drivers:** Simplifies external component requirements.  
- **Protection Features:** Overcurrent (OCP), overvoltage (OVP), and undervoltage (UVP) protection.  
- **Power-Good Output:** Monitors output voltage status.  
- **Soft-Start Function:** Prevents inrush current during startup.  

This information is based solely on the manufacturer's datasheet and technical documentation.
