Description and Introduction

PWM Controller, +5V or +12V Supply, VOUT =0.8V Min @ ?% Reg, Pentium, Pentium Pro, PowerPC and AlphaPC Microprocessors The ISL6522 is a dual MOSFET driver IC manufactured by **INTERSIL** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on available data:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Drive Voltage:** Up to 12V (for external MOSFETs)  
- **Switching Frequency:** Adjustable (typically up to 1MHz)  
- **Output Current (Peak):** 2A (source/sink)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 8-lead SOIC  

### **Descriptions:**
- Designed for synchronous buck converter applications.  
- Provides high-efficiency power conversion for voltage regulator modules (VRMs).  
- Includes two independent MOSFET drivers (high-side and low-side).  
- Features an integrated bootstrap diode for high-side drive.  

### **Features:**
- **Dual MOSFET Drivers:** Supports both high-side and low-side N-channel MOSFETs.  
- **Adjustable Dead-Time Control:** Prevents shoot-through in synchronous rectifiers.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Fast Rise/Fall Times:** Optimized for high-frequency switching.  
- **Bootstrap Diode:** Eliminates the need for an external diode.  
- **Low Power Consumption:** Enhances efficiency in power management applications.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed performance curves and application notes, refer to the official datasheet.
