- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin SOIC  

### **Descriptions:**  
The XRD5408AID is a synchronous buck regulator designed for high-efficiency power conversion in applications such as networking, telecom, and industrial systems. It integrates low-side and high-side MOSFETs, reducing external component count. The device supports adjustable output voltage and frequency, along with protection features like overcurrent and thermal shutdown.

### **Features:**  
- **Integrated Power MOSFETs** (low RDS(on))  
- **Adjustable Output Voltage** via external resistors  
- **Programmable Switching Frequency** (300kHz–1MHz)  
- **Soft-Start Function** to limit inrush current  
- **Overcurrent Protection (OCP)** and **Thermal Shutdown**  
- **Precision Reference Voltage (±1%)**  
- **Low Quiescent Current** in standby mode  

This information is strictly based on the manufacturer's datasheet and technical documentation.
