Description and Introduction

Advanced Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6420IAZ-TK is a synchronous buck PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Switching Frequency:** 300kHz (fixed)  
- **Output Current:** Up to 20A (with external MOSFETs)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead QSOP  

### **Descriptions:**
- The ISL6420IAZ-TK 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 includes integrated drivers for N-channel MOSFETs and supports adjustable soft-start and overcurrent protection.  

### **Features:**
- **Voltage-Mode Control:** Ensures stable operation with excellent transient response.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Adjustable Soft-Start:** Limits inrush current during startup.  
- **Overcurrent Protection (OCP):** Uses external current sensing for accurate fault detection.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within input voltage range.  
- **Power-Good Output:** Monitors output voltage status.  
- **Thermal Shutdown:** Protects the IC from overheating.  

This information is strictly based on the manufacturer's datasheet for the ISL6420IAZ-TK.
