Description and Introduction

1.2A Low Quiescent Current 1.5MHz High Efficiency Synchronous Buck Regulator The **ISL6273IRZ-T** is a high-efficiency, 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 0.6V to 5.5V  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Output Current:** Supports up to 25A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Lead QFN (5mm x 5mm)  

### **Descriptions:**  
- The ISL6273IRZ-T is a **voltage-mode PWM controller** designed for high-current, low-voltage applications.  
- It features **adaptive non-overlap gate drive** to prevent shoot-through in synchronous buck converters.  
- Includes **programmable soft-start** and **overcurrent protection** for enhanced system reliability.  

### **Features:**  
- **Adjustable switching frequency** (300kHz to 1MHz)  
- **Integrated MOSFET drivers** (high-side and low-side)  
- **Programmable current limit**  
- **Power-good output** for monitoring  
- **Synchronizable to external clock**  
- **Thermal shutdown protection**  
- **Under-voltage lockout (UVLO)**  

This information is sourced from the official **Intersil datasheet** for the ISL6273IRZ-T. No additional guidance or suggestions are included.
