- **Package:** 32-Pin TQFN (5mm x 5mm)  

### **Descriptions:**  
The MAX5098AATJ+ is a synchronous buck converter designed for high-voltage industrial, automotive, and telecom applications. It integrates high-side and low-side MOSFETs, reducing external component count. The device features cycle-by-cycle current limiting, thermal shutdown, and an adjustable soft-start for controlled power-up.  

### **Features:**  
- **Wide Input Voltage Range (4.5V to 76V)**  
- **Integrated High-Side and Low-Side MOSFETs**  
- **Adjustable Switching Frequency (200kHz to 2.2MHz)**  
- **Programmable Soft-Start**  
- **Cycle-by-Cycle Current Limiting**  
- **Thermal Shutdown Protection**  
- **Low Quiescent Current (40µA in Shutdown Mode)**  
- **Synchronous Operation for Higher Efficiency**  
- **Small Footprint (32-Pin TQFN Package)**  

This device is suitable for applications requiring high efficiency and compact power solutions, such as automotive systems, industrial controls, and telecom infrastructure.
