Description and Introduction

BiCMOS Cold Cathode Fluorescent Lamp Driver Controller 8-TSSOP -40 to 85 The UCC2973PWG4 is a power management IC manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments  
- **Category:** Power Management IC  
- **Package:** TSSOP-20  
- **Operating Temperature Range:** -40°C to +85°C  
- **Mounting Type:** Surface Mount  
- **Number of Pins:** 20  

### **Descriptions:**
The UCC2973PWG4 is a high-performance power factor correction (PFC) controller designed for AC/DC power supplies. It operates in continuous conduction mode (CCM) and provides precise regulation to improve power efficiency and reduce harmonic distortion.

### **Features:**
- **Power Factor Correction (PFC):** Supports CCM operation for improved efficiency.  
- **Voltage Feedforward:** Enhances transient response and stability.  
- **Programmable Switching Frequency:** Allows flexibility in design.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Current Limiting:** Protects against excessive current draw.  

This IC is commonly used in power supply applications requiring high efficiency and compliance with power quality standards.  

(Note: Always refer to the official Texas Instruments datasheet for detailed technical specifications.)
