### **Descriptions:**  
The UCC2808A-2Q1 is a high-performance current-mode PWM controller designed for DC-DC power supply applications. It is optimized for offline and DC-DC converters with fixed-frequency operation. The device includes features such as soft-start, current limiting, and under-voltage lockout (UVLO) for robust power management.  

### **Features:**  
- **Current-Mode Control:** Improves transient response and simplifies loop compensation.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within the supply voltage range.  
- **High-Current Totem-Pole Output:** Directly drives power MOSFETs.  
- **Fixed-Frequency Operation:** Up to 1MHz for compact designs.  
- **Low Startup Current:** Reduces power consumption during startup.  
- **Error Amplifier:** Provides precise voltage regulation.  
- **Leading-Edge Blanking:** Improves noise immunity in current sensing.  

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