Description and Introduction

Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6520CBZ is a switching regulator 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 12V  
- **Output Voltage Range:** Adjustable (via external components)  
- **Switching Frequency:** Up to 1MHz  
- **Output Current:** Supports high-current applications (external MOSFET dependent)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Pin SOIC (CBZ denotes the package type)  
- **Control Method:** Voltage-mode PWM control  

### **Descriptions:**  
- Designed for synchronous buck converter applications.  
- Provides high-efficiency power conversion for DC-DC voltage regulation.  
- Includes integrated drivers for external N-channel MOSFETs.  
- Features soft-start functionality to limit inrush current.  

### **Features:**  
- **Voltage-Mode Control:** Ensures stable output regulation.  
- **Adjustable Output Voltage:** Configured via external feedback resistors.  
- **Overcurrent Protection (OCP):** Prevents damage from excessive current.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within input voltage range.  
- **Soft-Start:** Reduces stress on components during startup.  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **High-Speed Switching:** Supports up to 1MHz operation.  

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