Description and Introduction

High Power-Factor Preregulator The UC3852DTR is a power factor correction (PFC) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 10V to 16V  
- **Operating Frequency:** Up to 250kHz  
- **Output Drive Current:** 1.5A (peak)  
- **Package Type:** SOIC-8  
- **Operating Temperature Range:** -40°C to +85°C  
- **Control Method:** Average Current Mode Control  
- **Start-Up Current:** 100µA (typical)  

### **Descriptions:**  
The UC3852DTR is designed for high-performance power factor correction in AC/DC power supplies. It features an average current mode control scheme to ensure low harmonic distortion and high power factor. The IC includes a precision multiplier, voltage amplifier, and current amplifier for accurate PFC regulation.  

### **Features:**  
- **Precision Multiplier/Divider:** Ensures low harmonic distortion.  
- **Average Current Mode Control:** Provides stable PFC operation.  
- **Low Start-Up Current:** Reduces power consumption during standby.  
- **Overvoltage Protection (OVP):** Protects the circuit from excessive output voltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Soft-Start Function:** Reduces inrush current during startup.  

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