- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC3807D-1 is a low-power, high-speed current-mode PWM controller designed for offline and DC-DC power supplies. It features a low start-up current and high-frequency operation, making it suitable for compact and efficient power conversion applications.  

### **Features:**  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Low Start-Up Current:** Enables quick power-up with minimal power consumption.  
- **Current-Mode Control:** Provides cycle-by-cycle current limiting for improved transient response.  
- **Programmable Soft-Start:** Reduces inrush current during start-up.  
- **Internal Leading-Edge Blanking:** Improves noise immunity in current sensing.  
- **100% Duty Cycle Capability:** Suitable for low-dropout applications.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.
