Description and Introduction

BiCMOS Cold Cathode Fluorescent Lamp Driver Controller 8-TSSOP -40 to 85 The UCC2972PWG4 is a power management IC manufactured by Texas Instruments (TI) or Burr-Brown (BB). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI) / Burr-Brown (BB)  
- **Part Number:** UCC2972PWG4  
- **Package:** TSSOP-16  
- **Type:** Power Management IC  
- **Function:** Power Factor Correction (PFC) Controller  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** Up to 20V  
- **Switching Frequency:** Adjustable (typically up to 500kHz)  
- **Control Method:** Average Current Mode Control  
- **Features:** Soft Start, Overvoltage Protection (OVP), Undervoltage Lockout (UVLO)  

### **Descriptions:**
The UCC2972PWG4 is a high-performance power factor correction (PFC) controller designed for AC/DC power supplies. It employs average current mode control to improve power factor and reduce harmonic distortion. The IC is optimized for use in boost converter topologies and includes protection features such as overvoltage and undervoltage lockout.

### **Features:**
- **Power Factor Correction (PFC):** Ensures compliance with harmonic standards (IEC 61000-3-2).  
- **Average Current Mode Control:** Provides stable operation with low distortion.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency and EMI performance.  
- **Soft Start:** Reduces inrush current during startup.  
- **Overvoltage Protection (OVP):** Safeguards against output voltage spikes.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low supply conditions.  
- **TSSOP-16 Package:** Compact footprint for space-constrained applications.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics, refer to the official datasheet.
