ST VIPer50B VIPer50BSP Manual(1)
The VIPer50B/BSP is a 400 V, 3 A SMPS primary integrated circuit that combines a PWM controller with a high‑voltage avalanche‑rugged MOSFET on a single silicon chip. It targets off‑line power supplies up to 50 W and offers features such as adjustable switching frequency, soft‑start, burst‑mode standby, and low standby power consumption.
The datasheet details absolute maximum ratings, thermal data, pin functions, electrical characteristics, oscillator and error‑amplifier sections, as well as mechanical dimensions for the PowerSO‑10 package. It also includes ordering information and recommended component values for typical applications.
