This document describes the features and characteristics of VIPer53DIP and VIPer53SP off-line primary switches, including high switching frequency, current limitation, current mode control with adjustable limitation, soft start and shut down control, automatic pulse skipping in standby mode, undervoltage lockout, and overtemperature protection. The product is suitable for off-line power supplies with high power capability.
The VIPer53 series combines an enhanced current‑mode PWM controller with a high‑voltage PowerSO‑10™ MOSFET in a compact DIP‑8 or PowerSO‑10 package. It is intended for off‑line power supplies with input ranges from 85 V to 265 V and provides up to 30 W (DIP‑8) or 65 W (PowerSO‑10) output power.
Key sections include pin‑function tables, absolute maximum ratings, thermal data, and detailed electrical characteristics for the supply, oscillator, error‑amplifier, PWM comparator, overload and over‑temperature protection circuits.
