Description and Introduction

0 The UCC2813QDR-2Q1 is a high-performance, BiCMOS power factor correction (PFC) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 10V to 17V  
- **Operating Frequency:** Up to 250 kHz  
- **Output Drive Current:** ±1.5A (peak)  
- **Supply Current:** 4 mA (typical)  
- **Duty Cycle Range:** 0% to 95%  
- **Soft-Start Time:** Programmable  
- **Package:** SOIC-8  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The UCC2813QDR-2Q1 is designed for power factor correction in AC/DC power supplies. It features a transition-mode (boundary conduction mode) control scheme, improving efficiency and reducing switching losses. It includes protections such as undervoltage lockout (UVLO), overvoltage protection (OVP), and peak current limiting.  

### **Features:**  
- **Transition-Mode PFC Operation**  
- **Low Distortion, Near-Unity Power Factor**  
- **Programmable Soft-Start**  
- **Peak Current Limiting**  
- **Undervoltage Lockout (UVLO)**  
- **Overvoltage Protection (OVP)**  
- **Low Start-Up and Operating Current**  
- **SOIC-8 Package for Space Efficiency**  

This device is commonly used in applications like power supplies, LED lighting, and industrial power systems requiring high power factor correction.
