Description and Introduction

ADVANCED PFC/PWM COMBINATION CONTROLLERS The UCC28515DWG4 is a power management IC manufactured by Texas Instruments (TEXAS). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Texas Instruments  
- **Category:** Power Management IC  
- **Type:** PFC and PWM Controller Combo  
- **Topology:** Boost (PFC), Flyback or Forward (PWM)  
- **Output Voltage:** Adjustable  
- **Switching Frequency:** Up to 250 kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-16 (DWG)  

### **Descriptions:**
The UCC28515DWG4 is a high-performance, integrated power factor correction (PFC) and pulse-width modulation (PWM) controller. It is designed for AC/DC power supplies with active PFC, combining both stages into a single IC for improved efficiency and reduced component count.  

### **Features:**
- **Integrated PFC and PWM Control:** Combines both functions in one IC.  
- **Average Current Mode PFC:** Ensures low distortion and high power factor.  
- **Voltage Mode PWM Controller:** Supports flyback or forward topologies.  
- **Programmable Switching Frequency:** Up to 250 kHz.  
- **Soft-Start Function:** Reduces inrush current.  
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup and shutdown.  
- **Low Startup Current:** Minimizes power consumption during startup.  

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