Description and Introduction

Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6526AIRZ 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:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 12V  
- **Output Voltage Range:** Adjustable from 0.9V 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 QFN (Quad Flat No-Lead)  

### **Descriptions:**
- The ISL6526AIRZ is designed for high-efficiency DC-DC conversion in synchronous buck topologies.  
- It integrates control, monitoring, and protection features for voltage regulator modules (VRMs).  
- Requires external N-channel MOSFETs for power stage implementation.  

### **Features:**
- **Precision Voltage Regulation:** ±1% accuracy over line, load, and temperature variations.  
- **Adjustable Soft-Start:** Prevents inrush current during startup.  
- **Overcurrent Protection (OCP):** Uses MOSFET RDS(ON) sensing.  
- **Overvoltage Protection (OVP):** Monitors output voltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within input voltage range.  
- **Power-Good (PG) Output:** Indicates stable output voltage.  
- **Synchronous Rectification:** Improves efficiency by reducing conduction losses.  

This information is strictly based on the manufacturer's datasheet for the ISL6526AIRZ.
