VIPer53E is a switch power supply chip produced by ST company. It has the characteristics of high switching frequency, adjustable current mode control, soft start and shutdown control, automatic burst mode, undervoltage lockout, integrated start-up current source, over-temperature protection, overload and short-circuit control, overvoltage protection.
The VIPer53E family combines a current‑mode PWM controller with a high‑voltage MOSFET in a single package. It is intended for offline power supplies up to 65 W, offering features such as soft‑start, burst‑mode standby, and multiple protection mechanisms.
The document provides electrical data, pin‑out diagrams, characteristic curves, and recommended external component values. It also includes mechanical dimensions, ordering information, and revision history for the VIPer53EDIP‑E (DIP‑8) and VIPer53ESP‑E (PowerSO‑10) versions.
