STMicroelectronics ViPer53DIP / VIPer53SP Datasheet
The ViPer53 series combines a current‑mode PWM controller with a high‑voltage Power MOSFET in a DIP‑8 or PowerSO‑10™ package. It offers features such as soft‑start, automatic burst mode, over‑temperature protection, and overload control, making it suitable for offline power supplies up to 30 W (DIP‑8) or 65 W (PowerSO‑10™).\n\nThe document provides pin descriptions, absolute maximum ratings, thermal data, and detailed electrical characteristics for both the ViPer53DIP and VIPer53SP variants, including switching frequency, voltage limits, and current specifications.
