- **Package:** 16-pin TSSOP (exposed pad)  
- **Protection Features:** Overcurrent, overtemperature, undervoltage lockout (UVLO)  
- **AEC-Q100 Qualified:** Yes (automotive-grade)  

### **Descriptions:**  
The MAX16903SAUE50/V+T is a synchronous buck converter designed for automotive applications, providing a stable 5V output from a wide input range. It integrates high-side and low-side MOSFETs for compact design and high efficiency.  

### **Features:**  
- Wide input voltage range (4.5V to 36V)  
- Synchronous rectification for improved efficiency  
- Adjustable soft-start  
- Low quiescent current (30µA in shutdown mode)  
- Fault protection (thermal shutdown, overcurrent)  
- Automotive-grade reliability (AEC-Q100 qualified)  

This device is suitable for automotive infotainment, ADAS, and other 12V/24V systems requiring a regulated 5V supply.
