Description and Introduction

BiCMOS Power Factor Preregulator 16-TSSOP -40 to 85 The UCC2818APWRG4 is a power factor correction (PFC) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 12V  
- **Operating Frequency:** Up to 250kHz  
- **Output Drive Current:** ±1.5A (peak)  
- **Supply Current:** 5mA (typical)  
- **Package Type:** TSSOP-20  
- **Operating Temperature Range:** -40°C to +105°C  

### **Descriptions:**  
The UCC2818APWRG4 is a high-performance, average current-mode PFC controller designed for boost converters. It features a wide input voltage range and supports continuous conduction mode (CCM) operation. The device includes protections such as undervoltage lockout (UVLO), overvoltage protection (OVP), and soft-start functionality.  

### **Features:**  
- **Average Current-Mode Control:** Ensures low distortion and high power factor.  
- **Programmable Switching Frequency:** Adjustable up to 250kHz.  
- **Low Start-Up Current:** Enables efficient operation.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Protection Features:** Includes UVLO, OVP, and cycle-by-cycle current limiting.  
- **TSSOP-20 Package:** Compact and suitable for space-constrained applications.  

This device is commonly used in AC/DC power supplies, industrial systems, and other applications requiring power factor correction.
