Description and Introduction

ADVANCED PFC/PWM COMBINATION CONTROLLERS The UCC28516N 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)  
- **Category:** PMIC - Power Factor Correction (PFC) Controllers  
- **Package:** PDIP-16  
- **Operating Temperature:** -40°C to 85°C  
- **Input Voltage Range:** 10V to 20V (VCC)  
- **Output Type:** PWM (Pulse Width Modulation)  
- **Switching Frequency:** Adjustable (typically up to 250kHz)  
- **Control Method:** Average Current Mode  
- **Maximum Duty Cycle:** 95%  
- **Features:** Soft Start, Overvoltage Protection (OVP), Undervoltage Lockout (UVLO)  

### **Descriptions:**  
The UCC28516N is a high-performance PFC controller designed for power supply applications requiring power factor correction. It operates in continuous conduction mode (CCM) and provides stable and efficient power factor correction with low harmonic distortion.  

### **Features:**  
- **Average Current Mode Control:** Ensures high power factor and low THD (Total Harmonic Distortion).  
- **Programmable Switching Frequency:** Allows optimization for efficiency and component size.  
- **Soft Start:** Reduces inrush current during startup.  
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Wide Operating Temperature Range:** Suitable for industrial applications.  

This information is based on TI's official documentation for the UCC28516N.
