Description and Introduction

Current Mode Push-Pull PWM With Programmable Slope Compensation The UCC28084D is a power factor correction (PFC) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 85 VAC to 265 VAC  
- **Switching Frequency:** Adjustable up to 300 kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  
- **Control Method:** Average Current Mode Control  
- **Supply Voltage (VCC):** 10 V to 17 V  
- **Peak Gate Drive Current:** ±1.5 A  
- **Power Factor:** >0.99  
- **Total Harmonic Distortion (THD):** <5%  

### **Descriptions:**  
The UCC28084D is a high-performance, continuous conduction mode (CCM) PFC controller designed for AC/DC power supplies. It features average current mode control for improved power factor correction and low harmonic distortion. The device includes protection features such as overvoltage protection (OVP), open-loop detection, and soft-start functionality.  

### **Features:**  
- **Average Current Mode Control** for high power factor  
- **Low THD** for compliance with IEC 61000-3-2 standards  
- **Adjustable Switching Frequency** (up to 300 kHz)  
- **Integrated Soft-Start** for controlled startup  
- **Overvoltage Protection (OVP)**  
- **Open-Loop Detection** for fault protection  
- **Low Startup and Operating Current**  
- **Lead (Pb)-Free and RoHS Compliant**  

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