Description and Introduction

BiCMOS Power Factor Preregulator The UCC2817DW is a power factor correction (PFC) controller IC manufactured by Texas Instruments (TI) and originally by Unitrode. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)/Unitrode  
- **Package:** SOIC-16 (DW)  
- **Input Voltage Range:** 10V to 17V (VCC operating range)  
- **Switching Frequency:** Adjustable up to 250 kHz  
- **Output Drive Current:** ±1.5A (peak)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Control Method:** Average current mode control  
- **Soft-Start Time:** Programmable  

### **Descriptions:**  
- The UCC2817DW is a high-performance, fixed-frequency PFC controller designed for boost-type power factor correction circuits.  
- It uses average current mode control to achieve near-unity power factor and low harmonic distortion.  
- Suitable for AC-DC power supplies, industrial systems, and applications requiring compliance with IEC 1000-3-2 standards.  

### **Features:**  
- **Fixed-Frequency Operation:** Ensures predictable noise performance.  
- **Average Current Mode Control:** Provides accurate input current shaping.  
- **Programmable Oscillator:** Adjustable switching frequency via external components.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup and shutdown.  
- **Overvoltage Protection (OVP):** Safeguards against output overvoltage.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **High-Current Totem Pole Output:** Directly drives power MOSFETs.  

This information is strictly based on the manufacturer's datasheet for factual accuracy.
