Description and Introduction

Improved Industry Standard Single Ended Current Mode PWM Controller The ISL6843IU is a high-performance synchronous buck PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 25V  
- **Output Voltage Range:** 0.8V to 5.5V (adjustable)  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead QFN (Quad Flat No-Lead)  

### **Descriptions:**
- The ISL6843IU is a voltage-mode PWM controller designed for synchronous buck DC-DC converters.  
- It provides high efficiency and precise regulation for power supply applications.  
- The device supports adjustable switching frequency and includes features for enhanced performance and protection.  

### **Features:**
- **Voltage-Mode Control:** Ensures stable and accurate output regulation.  
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Overcurrent Protection (OCP):** Safeguards against excessive load conditions.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within input voltage range.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Thermal Shutdown:** Protects the device from overheating.
