- **Gate Drive Voltage:** 8V (for N-channel MOSFETs)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 20-HTSSOP  

### **Descriptions:**  
The LM5118MHX/NOPB is a high-voltage buck controller designed for regulating low-voltage power supplies from high input voltage sources. It features peak current mode control for improved transient response and stability. The device includes an integrated high-side gate driver and requires an external low-side driver for synchronous rectification.  

### **Features:**  
- Wide input voltage range (4.5V to 65V)  
- Adjustable switching frequency (50kHz to 1MHz)  
- Programmable soft-start  
- Precision 0.8V reference  
- Cycle-by-cycle current limiting  
- Thermal shutdown protection  
- Adjustable line undervoltage lockout (UVLO)  
- Synchronizable to an external clock
