series introduction
# UCC28516DW Product Series Introduction
## 1. Overview
The UCC28516DW is a highly advanced and versatile integrated circuit (IC) product series designed specifically for power electronics applications. It plays a crucial role in power factor correction (PFC) circuits, which are essential for improving the efficiency and power quality of electrical systems. This product series is developed by Texas Instruments, a leading semiconductor company known for its high - quality and innovative electronic components.
## 2. Key Features
### 2.1 Power Factor Correction
- **High Power Factor**: The UCC28516DW is capable of achieving a very high power factor, typically greater than 0.99. This means that it can effectively convert the input AC power into DC power with minimal reactive power, reducing the overall power consumption and improving the efficiency of the electrical system.
- **Active PFC**: It utilizes an active power factor correction technique, which continuously adjusts the input current waveform to match the input voltage waveform. This results in a sinusoidal input current with low harmonic distortion, meeting the strictest international power quality standards such as IEC 61000 - 3 - 2.
### 2.2 Wide Input Voltage Range
- The product series can operate over a wide range of input voltages, typically from 85VAC to 265VAC. This makes it suitable for use in various global applications, as it can adapt to different mains voltages without the need for additional voltage - conversion circuitry.
### 2.3 High - Frequency Operation
- It supports high - frequency switching, allowing for the use of smaller and more cost - effective passive components such as inductors and capacitors. High - frequency operation also reduces the size and weight of the power supply, making it ideal for applications where space is limited, such as in portable electronics and compact power modules.
### 2.4 Comprehensive Protection Features
- **Over - Voltage Protection (OVP)**: The UCC28516DW is equipped with over - voltage protection circuitry that monitors the output voltage and shuts down the PFC circuit if the voltage exceeds a predefined safe level. This protects the downstream components from damage due to excessive voltage.
- **Over - Current Protection (OCP)**: It also has over - current protection, which detects excessive current flow in the circuit and takes appropriate action to limit the current. This helps prevent overheating and damage to the power components.
- **Under - Voltage Lockout (UVLO)**: The UVLO feature ensures that the circuit only operates when the input voltage is within a safe and stable range. If the input voltage drops below the specified threshold, the circuit is disabled to prevent improper operation.
### 2.5 Programmability
- The UCC28516DW offers a certain degree of programmability, allowing designers to optimize the performance of the PFC circuit according to specific application requirements. For example, parameters such as the switching frequency, output voltage, and current limit can be adjusted through external components.
## 3. Applications
### 3.1 Industrial Power Supplies
- In industrial settings, power supplies need to be highly efficient and reliable. The UCC28516DW can be used in industrial power supplies to improve the power factor, reduce energy consumption, and ensure stable operation. It is suitable for applications such as motor drives, industrial automation equipment, and power distribution systems.
### 3.2 Lighting Systems
- With the increasing demand for energy - efficient lighting solutions, the UCC28516DW is an ideal choice for lighting power supplies. It can be used in LED lighting systems to improve the power factor and reduce the harmonic distortion of the input current, ensuring compliance with lighting industry standards.
