Description and Introduction

Improved industry standard single-ended current mode PWM controller. The ISL6840IUZ-T is a high-performance 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 down to 0.8V  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Maximum Duty Cycle:** 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Lead MSOP (Mini Small Outline Package)  
- **Control Method:** Voltage Mode PWM  
- **Output Current:** Supports high-current applications (external MOSFETs required)  

### **Descriptions:**
- The ISL6840IUZ-T is designed for high-efficiency DC-DC conversion in applications such as telecom, networking, and industrial power supplies.  
- It provides precise voltage regulation and supports synchronous rectification for improved efficiency.  
- The device includes features like soft-start, overcurrent protection, and undervoltage lockout (UVLO).  

### **Features:**
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Programmable Soft-Start:** Prevents inrush current at startup.  
- **Overcurrent Protection (OCP):** Enhances system reliability.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Synchronous Rectification:** Improves efficiency by reducing conduction losses.  
- **Thermal Shutdown:** Protects the device from overheating.  

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