Description and Introduction

Advanced Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6420IRZ is a voltage regulator 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 28V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Output Current:** Up to 4A  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead QFN (5mm x 5mm)  

### **Descriptions:**
- The ISL6420IRZ is a synchronous buck PWM regulator designed for high-efficiency DC-DC conversion.  
- It integrates both high-side and low-side MOSFETs, reducing external component count.  
- Suitable for applications requiring precise voltage regulation and high current output.  

### **Features:**
- **Integrated MOSFETs:** Reduces board space and BOM cost.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Programmable Soft-Start:** Prevents inrush current.  
- **Overcurrent & Overtemperature Protection:** Enhances reliability.  
- **Power Good Indicator:** Monitors output status.  
- **Adjustable Switching Frequency:** Optimizes efficiency and noise performance.  

This information is strictly based on the manufacturer's datasheet for the ISL6420IRZ.
