Description and Introduction

Synchronizing Current Mode PWM for Subscriber Line Interface Circuits (SLICs) The ISL6401CR is a synchronous buck PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are the specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 24V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Switching Frequency:** 300kHz (adjustable)  
- **Output Current:** Up to 25A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SOIC  

### **Descriptions:**
- The ISL6401CR is a high-performance, voltage-mode PWM controller designed for synchronous buck DC-DC converters.  
- It provides precise regulation for high-current, low-voltage applications such as powering microprocessors, FPGAs, and ASICs.  
- The device integrates features like soft-start, overcurrent protection, and adjustable switching frequency.  

### **Features:**
- **Voltage-Mode Control:** Ensures stable and accurate output regulation.  
- **Adjustable Output Voltage:** Configurable via external resistors.  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Programmable Soft-Start:** Prevents inrush current at startup.  
- **Overcurrent Protection (OCP):** Safeguards against excessive load currents.  
- **Power-Good (PG) Output:** Monitors output voltage status.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency and component size.  
- **Low Shutdown Current:** Reduces power consumption when disabled.  

This information is based on the manufacturer's datasheet for the ISL6401CR.
