Description and Introduction

Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6526ACB is a PWM (Pulse Width Modulation) controller 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 Voltage Range:** Adjustable (via external components)  
- **Switching Frequency:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC (Small Outline Integrated Circuit)  
- **Number of Phases:** Single-phase  
- **Gate Drive Voltage:** 5V  

### **Descriptions:**
- The ISL6526ACB is a **voltage-mode PWM controller** designed for **DC-DC converter** applications.  
- It provides **precise regulation** for power supplies in computing and industrial systems.  
- Includes **overvoltage protection (OVP)** and **undervoltage lockout (UVLO)** for system safety.  
- Suitable for **synchronous buck converters** and other step-down topologies.  

### **Features:**
- **Voltage-Mode Control** for stable regulation.  
- **Programmable Soft-Start** to reduce inrush current.  
- **Error Amplifier with High Gain-Bandwidth** for fast transient response.  
- **Synchronous Rectification Support** for improved efficiency.  
- **Power-Good (PG) Output** for system monitoring.  
- **Low Standby Current** for energy efficiency.  

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