Description and Introduction

Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6527CB is a 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 5.5V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Switching Frequency:** 300kHz (typical)  
- **Duty Cycle:** Up to 100%  
- **Output Current:** Supports high-current applications (external MOSFET dependent)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SOIC  

### **Descriptions:**
- The ISL6527CB is a synchronous buck PWM controller designed for high-efficiency DC-DC voltage regulation.  
- It provides precise voltage regulation for applications such as power supplies for microprocessors, ASICs, and other low-voltage systems.  
- The controller includes features like soft-start, overcurrent protection, and undervoltage lockout (UVLO).  

### **Features:**
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Adjustable Output Voltage:** Configured using external feedback resistors.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Overcurrent Protection (OCP):** Safeguards against excessive load currents.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **High-Side and Low-Side MOSFET Drivers:** Integrated for synchronous buck topology.  
- **300kHz Fixed Frequency Operation:** Balances efficiency and component size.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed application notes or schematics, refer to the official datasheet from Renesas Electronics (formerly INTERSIL).
