Description and Introduction

0 The UCC3813D-5 is a power factor correction (PFC) controller manufactured by Texas Instruments (TI)/Unitrode. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)/Unitrode  
- **Type:** Power Factor Correction (PFC) Controller  
- **Package:** SOIC-16  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** 12V to 17V (recommended)  
- **Maximum Supply Voltage (VCC):** 18V  
- **Output Drive Current:** ±500mA (peak)  
- **Switching Frequency:** Adjustable (up to 250kHz)  
- **PWM Control Method:** Average Current Mode  
- **Power Factor Correction:** Near Unity  

### **Descriptions:**  
The UCC3813D-5 is a high-performance PFC controller designed for active power factor correction in AC-DC power supplies. It operates in continuous conduction mode (CCM) and employs average current mode control to achieve near-unity power factor. The device includes features like soft-start, overvoltage protection, and current limiting for robust operation.  

### **Features:**  
- **Average Current Mode Control** for improved power factor correction  
- **Programmable Switching Frequency** (up to 250kHz)  
- **Low Start-Up Current** (<150µA)  
- **Soft-Start Function** for controlled startup  
- **Overvoltage Protection (OVP)**  
- **Undervoltage Lockout (UVLO)**  
- **Peak Current Limiting**  
- **Zero Power Detection** for improved light-load efficiency  
- **High-Current Totem Pole Output** (±500mA)  
- **SOIC-16 Package** for compact designs  

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