Description and Introduction

Advanced PFC/PWM Combination Controllers The UCC28515DW is a Power Factor Correction (PFC) controller manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Package:** SOIC-16 (DW)  
- **Type:** Average Current Mode PFC Controller  
- **Input Voltage Range:** Not explicitly stated (typically designed for universal AC input)  
- **Switching Frequency:** Adjustable (exact range not specified)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** Typically up to 20V  
- **Control Method:** Average Current Mode Control  
- **Output Drive Capability:** Totem-pole output for driving external MOSFETs  

### **Descriptions:**  
The UCC28515DW is a high-performance PFC controller designed to improve power factor in AC-DC power supplies. It uses average current mode control to regulate the input current waveform, ensuring compliance with power quality standards.  

### **Features:**  
- **Power Factor Correction (PFC):** Ensures near-unity power factor.  
- **Average Current Mode Control:** Provides precise input current shaping.  
- **Low Distortion:** Minimizes input current harmonics.  
- **Overvoltage Protection (OVP):** Protects against output overvoltage conditions.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup and shutdown.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **External Synchronization Capability:** Allows synchronization with other switching circuits.  
- **Totem-Pole Gate Drive:** Supports direct MOSFET driving.  

This information is strictly based on the available knowledge base without additional interpretation.
