Description and Introduction

PFC Controller for low to medium power applications requiring compliance with IEC 1000-3-2 The UCC28051D is a power factor correction (PFC) controller manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments  
- **Category:** PMIC - Power Factor Correction  
- **Package:** SOIC-8  
- **Operating Temperature:** -40°C to +105°C  
- **Input Voltage Range:** 10.5V to 22V  
- **Switching Frequency:** Adjustable up to 300kHz  
- **Output Voltage Regulation:** Adjustable via external components  
- **Peak Current Limit:** Programmable  
- **Startup Current:** Low (typically 60µA)  

### **Descriptions:**
The UCC28051D is a high-performance, continuous conduction mode (CCM) PFC controller designed for AC/DC power supplies. It provides active power factor correction to meet regulatory standards such as IEC 61000-3-2. The device features a transition-mode operation for improved efficiency and reduced switching losses.

### **Features:**
- **Average Current Mode Control:** Ensures low distortion and high power factor.  
- **Programmable Switching Frequency:** Allows optimization for efficiency and component size.  
- **Internal Start-Up Timer:** Ensures controlled soft-start operation.  
- **Overvoltage Protection (OVP):** Safeguards against output voltage spikes.  
- **Undervoltage Lockout (UVLO):** Prevents operation at insufficient supply voltages.  
- **Zero Current Detection (ZCD):** Ensures transition-mode operation for improved efficiency.  
- **Low Total Harmonic Distortion (THD):** Enhances compliance with power quality standards.  

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