Description and Introduction

Advanced PFC/PWM Combination Controllers 20-SOIC -40 to 105 The UCC28514DWG4 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  
- **Category:** PMIC - Power Factor Correction  
- **Package:** SOIC-16  
- **Operating Temperature Range:** -40°C to 85°C  
- **Input Voltage Range:** 10V to 20V  
- **Output Voltage:** Adjustable  
- **Switching Frequency:** Up to 250kHz  
- **Control Method:** Average Current Mode  
- **Topology:** Boost  

### **Descriptions:**
The UCC28514DWG4 is a high-performance PFC controller designed for power supply applications requiring power factor correction. It operates in continuous conduction mode (CCM) and provides precise current shaping to improve power factor and reduce harmonic distortion.

### **Features:**
- **Average Current Mode Control:** Ensures low distortion and high power factor.  
- **Programmable Switching Frequency:** Allows optimization for efficiency and EMI performance.  
- **Overvoltage Protection (OVP):** Protects against output voltage surges.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Low Start-Up Current:** Minimizes power consumption during initialization.  
- **Zero Current Detection (ZCD):** Ensures efficient operation in CCM.  

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