Description and Introduction

Current Mode Push-Pull PWM With Programmable Slope Compensation The UCC28086PW is a PFC (Power Factor Correction) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Transition Mode (TM) PFC  
- **Input Voltage Range:** 85 VAC to 265 VAC  
- **Output Voltage Range:** Up to 400 VDC  
- **Switching Frequency:** Adjustable (typically up to 300 kHz)  
- **Driver Output Current:** ±1.5 A peak  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** TSSOP-20 (PW)  

### **Descriptions:**  
The UCC28086PW is a high-performance, transition-mode PFC controller designed for AC-DC power supplies. It features a natural frequency modulation technique to improve efficiency and reduce EMI. The controller includes critical conduction mode operation, ensuring high power factor and low THD (Total Harmonic Distortion).  

### **Features:**  
- **Natural Interleaving™ Technology:** Enables two-phase operation for reduced input/output ripple.  
- **Average Current Mode Control:** Ensures low THD and high power factor.  
- **Programmable Switching Frequency:** Allows optimization for efficiency and EMI performance.  
- **Integrated High-Current Gate Driver:** Supports MOSFETs directly.  
- **Protection Features:** Includes overvoltage (OVP), undervoltage (UVP), and open-loop protection.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Low Standby Power Consumption:** Enhances efficiency in light-load conditions.  

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