Description and Introduction

High Frequency Synchronous PWM Buck Controller in a 10-Lead MLPD Package. The IR3624M is a synchronous buck regulator from International Rectifier (IR). Here are the key specifications, descriptions, and features from the manufacturer:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 24V  
- **Output Voltage Range:** 0.6V to 5.5V (adjustable via external resistors)  
- **Output Current:** Up to 4A  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead PQFN (5mm x 6mm)  

### **Descriptions:**
- The IR3624M is a high-efficiency, synchronous step-down DC-DC regulator designed for high-performance applications.  
- It integrates high-side and low-side MOSFETs, reducing external component count.  
- Features a voltage-mode control architecture with adjustable switching frequency.  

### **Features:**
- **Integrated Power MOSFETs:** Reduces board space and BOM cost.  
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Soft-Start:** Prevents inrush current during startup.  
- **Overcurrent Protection (OCP):** Safeguards against excessive load conditions.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Wide Input Voltage Range:** Supports various power sources.
