Description and Introduction

Improved industry standard single-ended current mode PWM controller. The ISL6841IUZ is a high-performance synchronous buck PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable down to 0.6V  
- **Switching Frequency:** 200kHz to 1MHz (adjustable)  
- **Duty Cycle Range:** 0% to 100%  
- **Peak Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Lead MSOP  

### **Descriptions:**
- The ISL6841IUZ is designed for high-efficiency DC-DC power conversion in applications such as telecom, industrial, and computing systems.  
- It supports synchronous rectification for improved efficiency and includes adaptive dead-time control to minimize body diode conduction losses.  
- The controller operates in voltage-mode control with an external compensation network for flexible loop tuning.  

### **Features:**
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Precision Reference:** 0.6V ±1% accuracy over temperature.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Soft-Start:** Programmable to limit inrush current.  
- **Protection Features:**  
  - Overcurrent protection (OCP)  
  - Overvoltage protection (OVP)  
  - Undervoltage lockout (UVLO)  
- **Synchronous Operation:** Enhances efficiency by replacing the freewheeling diode with a low-side MOSFET.  

This device is suitable for point-of-load (POL) regulators and other power supply applications requiring high efficiency and flexible design.  

(Note: Always refer to the latest datasheet for detailed specifications and application guidelines.)
