### **Descriptions:**  
The UCC3808AD-2 is a high-performance current-mode PWM controller designed for DC-DC converter applications. It provides precise regulation with features such as cycle-by-cycle current limiting and undervoltage lockout (UVLO).  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Programmable Oscillator:** Allows flexible frequency setting via external components.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **High-Current Totem-Pole Output:** Directly drives power MOSFETs.  
- **Low Startup Current:** Reduces power consumption during initial operation.  

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