UC2854BDW Allgemeine Beschreibung

The UC2854BDW is a highly integrated pulse width modulation controller designed specifically for controlling isolated power supplies. It features a high voltage start-up circuit, current limiting, soft start, and a frequency shift control to improve the efficiency of the power supply. This device operates over a wide input voltage range and provides a fixed frequency pulse width modulation control for controlling a power stage. The soft start function helps to prevent excessive inrush current during start-up, while the frequency shift control allows for improved efficiency over a wide load range.The UC2854BDW also includes under-voltage lockout, over-current protection, and thermal shutdown features to protect the power supply and ensure safe operation. It is available in a 16-pin SOIC package, making it suitable for a wide range of applications, including industrial power supplies, battery chargers, and lighting applications.
