VIPer53E is a switching power supply chip produced by ST company. It uses a high voltage MDMesh Power MOSFET and has overload and short-circuit protection. The input voltage range is wide and the power output range is large.
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 overload protection.
The document provides electrical ratings, thermal data, pin functions, and typical performance characteristics, including switching frequency up to 300 kHz and supply voltage range of 0‑19 V.
