Description and Introduction

Current Mode Push-Pull PWM With Programmable Slope Compensation 8-SOIC -40 to 85 The UCC28083DG4 is a PFC (Power Factor Correction) controller 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)  
- **Category:** PMIC - Power Factor Correction Controllers  
- **Package:** SOIC-8  
- **Operating Temperature:** -40°C to +105°C  
- **Mounting Type:** Surface Mount  
- **Output Type:** Transistor Driver  
- **Topology:** Boost  
- **Switching Frequency:** Adjustable (typically up to 300 kHz)  
- **Voltage Supply (Vcc):** 10.5V to 18V  
- **Current - Startup:** 50 µA (typical)  

### **Descriptions:**  
The UCC28083DG4 is an advanced continuous conduction mode (CCM) PFC controller designed for high-efficiency power factor correction in AC-DC power supplies. It features an average current mode control architecture, ensuring low harmonic distortion and high power factor. The device is optimized for universal input voltage range applications.

### **Features:**  
- **Average Current Mode Control** for low THD (Total Harmonic Distortion)  
- **Programmable Switching Frequency** for design flexibility  
- **Internal Start-Up Timer** for controlled soft-start  
- **Overvoltage Protection (OVP)**  
- **Open-Loop Protection (OLP)**  
- **Undervoltage Lockout (UVLO)**  
- **Low Power Consumption** during standby  
- **Lead (Pb)-Free and RoHS Compliant**  

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