Description and Introduction

Low Power Economy BiCMOS Current Mode PWM 8-SOIC -40 to 85 The UCC2813DTR-2G4 is a high-performance, continuous conduction mode (CCM) power factor correction (PFC) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 10V to 17V  
- **Operating Frequency:** Adjustable up to 250kHz  
- **Duty Cycle Range:** 0% to 95%  
- **Supply Current (Typical):** 3.5mA  
- **Output Drive Current:** ±1.5A (peak)  
- **Error Amplifier Bandwidth:** 5MHz  
- **Package:** SOIC-8  
- **Operating Temperature Range:** -40°C to +105°C  

### **Descriptions:**  
The UCC2813DTR-2G4 is designed for power factor correction in AC/DC power supplies, ensuring near-unity power factor and low harmonic distortion. It operates in continuous conduction mode (CCM) and features a high-speed PWM controller with a totem-pole output stage for driving external MOSFETs.  

### **Features:**  
- **Average Current Mode Control** for improved noise immunity  
- **Programmable Switching Frequency**  
- **Under-Voltage Lockout (UVLO)**  
- **Over-Voltage Protection (OVP)**  
- **Soft-Start Function**  
- **Low Start-Up Current**  
- **High-Bandwidth Error Amplifier** for fast transient response  

This device is commonly used in applications such as:  
- AC/DC power supplies  
- LED lighting drivers  
- Industrial power systems
