### **Descriptions:**  
The LM5020MM-1/NOPB is a pulse-width modulation (PWM) controller designed for high-voltage applications. It supports buck, flyback, and forward converter topologies and operates over a wide input voltage range (9V to 75V). It includes features like soft-start and enable control for power management.

### **Features:**  
- Wide input voltage range (9V to 75V)  
- Adjustable switching frequency (50kHz to 1MHz)  
- High-duty-cycle operation (up to 95%)  
- Programmable soft-start  
- Enable/disable control  
- Under-voltage lockout (UVLO)  
- Current-mode control architecture  
- Available in a small MSOP-10 package  

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