Description and Introduction

Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6526AIR is a synchronous buck PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 25V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Switching Frequency:** 300kHz (fixed)  
- **Output Current:** Supports high-current applications (external MOSFETs required)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead QSOP  

### **Descriptions:**  
- The ISL6526AIR is designed for DC-DC voltage regulation in synchronous buck converter applications.  
- It integrates a high-performance PWM controller with precision voltage reference and error amplifier.  
- Supports adjustable output voltage through external resistor dividers.  
- Includes overcurrent protection (OCP), undervoltage lockout (UVLO), and power-good monitoring.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by replacing the freewheeling diode with a low-side MOSFET.  
- **Voltage Feed-Forward Compensation:** Enhances transient response.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Power-Good (PG) Output:** Monitors output voltage status.  
- **Adjustable Current Limit:** Configurable via an external resistor.  
- **Low Standby Current:** Optimized for power-saving applications.  

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