Description and Introduction

Latchable Negative Floating Single, Hot-Swap IC Industrial Temp. 8-SOIC -40 to 85 The UCC2921DG4 is a Power Factor Correction (PFC) controller manufactured by Texas Instruments (TI)/Burr-Brown (BB).  

### **Specifications:**  
- **Input Voltage Range:** Typically operates with a wide input range suitable for PFC applications.  
- **Output Voltage:** Adjustable based on external components.  
- **Switching Frequency:** Programmable via external resistor.  
- **Operating Temperature Range:** -40°C to +85°C.  
- **Package:** SOIC-8 (DG4).  

### **Descriptions:**  
The UCC2921DG4 is designed for high-efficiency power factor correction in AC/DC power supplies. It provides control for boost-type PFC circuits, improving power quality by shaping the input current waveform to match the input voltage.  

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

This information is based solely on the manufacturer's documented specifications.
