Description and Introduction

Single Synchronous Buck Pulse-Width Modulation PWM Controller The ISL6520BCBZ is a power supply controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** INTERSIL (now Renesas Electronics)  
- **Part Number:** ISL6520BCBZ  
- **Package:** 16-Lead QSOP (Quad Flat Small Outline Package)  
- **Operating Voltage Range:** 4.5V to 5.5V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Switching Frequency:** Up to 1MHz  
- **Number of Outputs:** Dual (PWM controllers for two synchronous buck converters)  
- **Current Limit Protection:** Yes  
- **Thermal Shutdown Protection:** Yes  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The ISL6520BCBZ is a dual synchronous buck PWM controller designed for generating regulated supply voltages in high-performance applications. It provides precise voltage regulation for two independent outputs, making it suitable for motherboards, graphics cards, and other power management systems.  

### **Features:**
- **Dual PWM Controllers:** Independently regulates two synchronous buck converters.  
- **Adjustable Output Voltage:** Configured using external feedback resistors.  
- **High Efficiency:** Uses synchronous rectification for improved power conversion.  
- **Overcurrent Protection:** Monitors and limits output current.  
- **Thermal Shutdown:** Protects the IC from overheating.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Wide Input Voltage Range:** Supports 4.5V to 5.5V input.  
- **1MHz Switching Frequency:** Enables compact power supply designs.  

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