Power Factor Correction (PFC) is a power scale technology used in electrical and electronic systems to improve their power utilization efficiency. PFC is achieved by the use of a power electronics device, such as the UCC28521DWR, which is designed to correct the power factor of a particular system by actively cancelling out harmonics components that would otherwise cause a loss in system efficiency.

The UCC28521DWR is a two-channel single stage PFC controller that can be used to improve accuracy and system efficiency in applications including small appliances, lighting, large appliances, and general purpose AC-DC conversion. The device features two independently-controlled AC channels, allowing for both single and multiple stage PFC circuitry for improved efficiency and power savings. In addition, the UCC28521DWR includes a variety of integrated features such as over-voltage protection, thermal shut down, and simultaneous PWM control.

The UCC28521DWR can be easily configured, allowing for improved performance and steady operation in a variety of conditions. The device utilizes a fixed-frequency, power factor correction (PFC) method, allowing for smooth, low losses in a range of output power. The UCC28521DWR also offers current mode control and constant output power operation, providing improved system performance and stability. By utilizing the device’s dual-mode PFC controller, users can achieve single and multi-stage PFC solutions.

The UCC28521DWR incorporates a programmable under-voltage lockout (UVLO) feature that allows for improved system efficiency and performance. The UVLO feature protects the PFC circuitry from over-voltage conditions, automatically controlling the startup and shutdown of the power supply. The device also includes integrated over-voltage protection for safe and reliable operation.

The UCC28521DWR allows for flexible operation, with adjustable soft start and frequency compensation. The device also features a low-power stand-by mode, which allows for improved efficiency in standby applications. Additionally, the device supports wide input voltage ranges, allowing for improved flexibility and compatibility with a variety of applications and systems.

The UCC28521DWR is an ideal solution for power factor correction applications, offering improved accuracy, efficiency and stability. The device is easy to configure and provides a variety of features and options for optimal system performance. Combined with its wide input voltage range and adjustable soft start and frequency compensation, the UCC28521DWR is an excellent choice for a variety of system applications.
