Description and Introduction

1 The UC285T-1 is a power factor correction (PFC) controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on the available knowledge:

### **Specifications:**  
- **Input Voltage Range:** Typically operates with high-voltage inputs for PFC applications.  
- **Output Voltage Regulation:** Designed for power factor correction in AC-DC converters.  
- **Switching Frequency:** Adjustable, often in the range of tens to hundreds of kHz.  
- **Operating Temperature Range:** Industrial-grade, typically -40°C to +85°C.  
- **Package Type:** TO-220 (through-hole package).  
- **Control Method:** Average current mode control for improved power factor correction.  

### **Descriptions:**  
- The UC285T-1 is a dedicated PFC controller optimized for high-efficiency power supplies.  
- It is part of TI’s UCx85 series, known for robust performance in power management applications.  
- Suitable for offline power supplies, industrial systems, and other AC-DC conversion needs.  

### **Features:**  
- **Power Factor Correction (PFC):** Ensures near-unity power factor for compliance with standards like IEC 61000-3-2.  
- **Average Current Mode Control:** Reduces input current distortion.  
- **Overvoltage Protection (OVP):** Safeguards against output overvoltage conditions.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup and shutdown behavior.  
- **Programmable Oscillator:** Allows flexibility in setting switching frequency.  
- **Low Distortion:** Minimizes harmonic content in the input current.  

This information is based on TI’s documentation for the UC285T-1. For precise details, always refer to the official datasheet.
