Description and Introduction

XPHASE Control IC. The IR3081MTRPBF is a power management IC (PMIC) manufactured by Infineon Technologies. It is a synchronous buck controller designed for high-performance voltage regulation applications.  

### **Key Specifications:**  
- **Input Voltage Range:** 4.5V to 21V  
- **Output Voltage Range:** Adjustable (typically 0.6V to 5.5V)  
- **Switching Frequency:** Adjustable (300kHz to 1MHz)  
- **Maximum Output Current:** Supports high-current applications (exact value depends on external components)  
- **Efficiency:** High efficiency with synchronous rectification  
- **Package:** 6x6 mm, 28-pin QFN  

### **Descriptions and Features:**
