- **UVLO (Undervoltage Lockout):** 8.5V (Turn-On), 7.6V (Turn-Off)  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** VSSOP-8 (DGK)  

### **Descriptions:**  
The UCC28C41DGKRG4 is designed for high-frequency switching power supplies, offering precise control in current-mode applications. It features a high-speed error amplifier, adjustable oscillator frequency, and cycle-by-cycle current limiting for robust performance.  

### **Features:**  
- **Current-Mode Control** for improved transient response  
- **Programmable Soft-Start** for controlled startup  
- **Synchronizable Oscillator** for multi-phase operation  
- **Internal Leading-Edge Blanking** for noise immunity  
- **Low Startup and Operating Current**  
- **Under-Voltage Lockout (UVLO)** for protection  
- **Totem-Pole Output** for direct MOSFET drive  

This device is commonly used in offline and DC-DC power supplies, telecom systems, and industrial applications.
