Description and Introduction

Advanced PFC/PWM Combination Controllers The UCC28517DW is a power factor correction (PFC) controller manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments  
- **Package:** SOIC-16 (DW)  
- **Type:** Power Factor Correction (PFC) Controller  
- **Input Voltage Range:** 85V to 265V AC  
- **Switching Frequency:** Adjustable up to 250 kHz  
- **Output Voltage:** Typically 400V DC  
- **Operating Temperature Range:** -40°C to 125°C  
- **Control Method:** Average Current Mode Control  
- **Supply Voltage (VCC):** 12V to 20V  
- **Peak Gate Drive Current:** ±1.5A  

### **Descriptions:**
The UCC28517DW is a high-performance PFC controller designed for boost-type power factor correction applications. It uses average current mode control to achieve near-unity power factor and low harmonic distortion. The device is optimized for universal input voltage range (85V–265V AC) and is commonly used in power supplies, LED drivers, and industrial systems.

### **Features:**
- **Power Factor Correction (PFC):** Ensures compliance with IEC 61000-3-2 standards.  
- **Average Current Mode Control:** Provides high power factor and low THD.  
- **Programmable Switching Frequency:** Up to 250 kHz.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Overvoltage Protection (OVP):** Protects against output overvoltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low supply conditions.  
- **High Gate Drive Output:** Supports fast switching of external MOSFETs.  
- **Low Startup Current:** Reduces power consumption during startup.  

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