Description and Introduction

1.2A Low Quiescent Current 1.6MHz High Efficiency Synchronous Buck Regulator The ISL6273 is a high-efficiency, synchronous buck PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Output Current:** Supports high current with external MOSFETs  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead QFN (4mm x 4mm)  

### **Descriptions:**
The ISL6273 is designed for high-performance DC-DC voltage regulation in applications such as notebooks, servers, and telecom systems. It features adaptive non-overlapping gate drivers and supports synchronous rectification for improved efficiency.  

### **Features:**
- **Adjustable Output Voltage:** Via external resistor divider  
- **Programmable Soft-Start:** Reduces inrush current  
- **Power-Good Output:** Monitors output voltage status  
- **Overcurrent Protection:** Prevents damage during faults  
- **Overvoltage Protection (OVP):** Safeguards the load  
- **Undervoltage Lockout (UVLO):** Ensures proper startup  
- **Synchronizable Clock Input:** Reduces noise in multi-phase systems  

This information is based on the manufacturer's datasheet. For detailed application notes or design support, refer to Renesas Electronics' official documentation.
