- **Package:** TO-263 (D2PAK)  

### **Description:**
The IRU3027CW is a synchronous buck regulator designed for high-efficiency step-down voltage conversion. It integrates high-side and low-side MOSFETs, reducing external component count. It is suitable for a wide range of applications, including industrial, automotive, and consumer electronics.

### **Features:**
- **Integrated Power MOSFETs:** Reduces external component requirements.  
- **Adjustable Output Voltage:** Via external resistor divider.  
- **Overcurrent Protection:** Prevents damage during overload conditions.  
- **Thermal Shutdown:** Protects the IC from overheating.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within input voltage range.  
- **Low Quiescent Current:** Improves efficiency at light loads.  

For detailed application notes and circuit configurations, refer to the official IRU3027CW datasheet.
