Description and Introduction

0 The UCC3813DTR-1 is a BiCMOS power factor correction (PFC) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 5.5V  
- **Operating Frequency:** Up to 250 kHz  
- **Output Drive Current:** ±1.5A (peak)  
- **Power Factor Correction:** Yes  
- **Package Type:** SOIC-8  
- **Operating Temperature Range:** -40°C to +85°C  
- **Control Method:** Average Current Mode  
- **Start-Up Current:** 150 µA (typical)  

### **Descriptions:**  
The UCC3813DTR-1 is designed for high-performance power factor correction in AC/DC power supplies. It features a BiCMOS process for low power consumption and high-speed operation. The device includes an average current mode control loop for precise current shaping and low distortion.  

### **Features:**  
- **Low Power Consumption:** Optimized for efficiency.  
- **Precision Reference:** 5V ±1% accuracy.  
- **Soft-Start Function:** Reduces inrush current.  
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup and shutdown.  
- **Zero Current Detection (ZCD):** Supports discontinuous conduction mode (DCM) operation.  
- **High-Speed Driver:** Supports fast-switching MOSFETs.
