The VIPer53‑E is an offline primary switch controller designed for wide‑range input voltages (85‑265 V) and high‑voltage applications up to 620 V. It integrates a high‑voltage MOSFET, current‑mode control, soft‑start, overload and over‑temperature protection, and offers a switching frequency up to 300 kHz.
The document provides absolute maximum ratings, thermal data, detailed electrical characteristics, pin descriptions, and example configurations for primary regulation and secondary feedback. It also includes recommended external components for protection and timing, as well as revision history.
