Description and Introduction

1 The UC385T-2 is a power factor correction (PFC) controller manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** UC385T-2  
- **Type:** Power Factor Correction (PFC) Controller  
- **Package:** TO-220 (Through-Hole)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** Designed for high-voltage applications (exact range depends on external components)  
- **Switching Frequency:** Adjustable (typically up to several hundred kHz)  
- **Control Method:** Average Current Mode Control  

### **Descriptions:**  
The UC385T-2 is a high-performance PFC controller designed to improve power factor in AC/DC power supplies. It uses average current mode control to regulate input current in phase with input voltage, ensuring high power factor correction. It is commonly used in offline power supplies, industrial systems, and other applications requiring compliance with power quality standards.  

### **Features:**  
- **Power Factor Correction (PFC):** Ensures near-unity power factor.  
- **Average Current Mode Control:** Provides precise current shaping.  
- **Programmable Oscillator:** Allows adjustable switching frequency.  
- **Overvoltage Protection (OVP):** Protects against output overvoltage conditions.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup and shutdown.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **High Drive Output:** Capable of driving external MOSFETs or IGBTs.  
- **Low Distortion:** Minimizes harmonic distortion in the input current.  

This information is strictly based on Ic-phoenix technical data files for the UC385T-2 from Texas Instruments.
