Description and Introduction

High Frequency 2-Phase Single or Dual Output Sychronous Step Down Controller with Output Tracking and Sequencing The IR3622MTRPBF is a synchronous buck PWM controller manufactured by Infineon Technologies (formerly International Rectifier). Here are the key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 24V  
- **Output Voltage Range:** Adjustable from 0.7V up to 85% of VIN  
- **Switching Frequency:** 300kHz (fixed)  
- **Output Current:** Supports high current with external MOSFETs  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead PQFN (5mm x 5mm)  

### **Descriptions:**
- The IR3622MTRPBF is designed for high-efficiency DC-DC step-down applications.  
- It integrates a synchronous buck controller with advanced features for power management.  
- Suitable for point-of-load (POL) regulation in computing, telecom, and industrial applications.  

### **Features:**
- **Precision Voltage Reference:** ±1% accuracy over temperature.  
- **Integrated MOSFET Drivers:** Supports N-channel MOSFETs.  
- **Programmable Soft-Start:** Reduces inrush current.  
- **Overcurrent Protection (OCP):** Uses external sense resistor.  
- **Overvoltage Protection (OVP):** Prevents damage to the load.  
- **Undervoltage Lockout (UVLO):** Ensures stable operation.  
- **Power Good Indicator:** Monitors output status.  
- **Thermal Shutdown:** Protects against overheating.  

This controller is optimized for high-performance power conversion with minimal external components.
