Description and Introduction

Highly Efficient Integrated 12A Sync Buck Regulator The IR3840M is a synchronous buck regulator manufactured by International Rectifier (IR). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
International Rectifier (IR)  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 21V  
- **Output Voltage Range:** 0.6V to 17V (adjustable via external resistors)  
- **Output Current:** Up to 40A  
- **Switching Frequency:** 300 kHz to 1 MHz (programmable)  
- **Efficiency:** Up to 95%  
- **Control Method:** Voltage Mode Control  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 40-Lead PQFN (6mm x 6mm)  

### **Descriptions:**  
- The IR3840M is a high-performance, synchronous buck regulator designed for high-current, high-efficiency applications.  
- It integrates high-side and low-side MOSFET drivers, reducing external component count.  
- Features advanced control algorithms for fast transient response and stable operation.  

### **Features:**  
- **Integrated MOSFET Drivers:** Reduces external components and PCB space.  
- **Programmable Switching Frequency:** Allows optimization for efficiency and component size.  
- **Adjustable Soft-Start:** Prevents inrush current issues.  
- **Overcurrent Protection (OCP):** Prevents damage during fault conditions.  
- **Overvoltage Protection (OVP):** Safeguards the load from excessive voltage.  
- **Thermal Shutdown:** Protects the IC from overheating.  
- **Precision Reference Voltage:** 0.6V ±1% accuracy for tight output regulation.  
- **Power Good Indicator:** Monitors output voltage status.
