- **Peak Gate Drive Current:** ±1.5 A  

### **Descriptions:**  
The UCC28019DR is a high-performance, transition-mode PFC controller designed for AC-DC power supplies. It features average current mode control for improved power factor correction and low THD (Total Harmonic Distortion).  

### **Features:**  
- **Low THD & High PF:** Optimized for near-unity power factor.  
- **Internal Start-up Timer:** Reduces external component count.  
- **Overvoltage Protection (OVP):** Safeguards against output overvoltage.  
- **Brownout Protection:** Detects low input voltage conditions.  
- **Soft-Start:** Minimizes inrush current.  
- **Zero Current Detection (ZCD):** Ensures transition-mode operation.  
- **Programmable Switching Frequency:** Allows design flexibility.  

This controller is commonly used in power supplies for applications such as LED lighting, industrial systems, and consumer electronics.
