Description and Introduction

6A Dual Synchronous Buck Regulator with Integrated MOSFETs The ISL65426HRZ is a 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 25V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** Adjustable from 100kHz to 1MHz  
- **Output Current:** Supports high-current applications (external FETs required)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-Lead QFN (5mm x 5mm)  

### **Descriptions:**
- The ISL65426HRZ is a **dual-output, synchronous buck PWM controller** designed for high-performance power supply applications.  
- It provides **precise voltage regulation** and supports **voltage tracking** for sequencing requirements.  
- The device includes **adaptive non-overlapping gate drivers** to prevent shoot-through in external MOSFETs.  

### **Features:**
- **Dual-Output Control:** Independently regulates two power rails.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency and component size.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Power-Good Output:** Monitors output voltage status.  
- **Overcurrent Protection (OCP):** Uses inductor DCR or sense resistors for current limiting.  
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  

This device is commonly used in **servers, telecom equipment, and industrial power systems** requiring high-efficiency DC-DC conversion.  

*(Note: Always refer to the latest datasheet from Renesas for detailed specifications and application notes.)*
