Str-z2062 Datasheet Here

The IC is a "custom microcircuit" that simplifies power supply design by combining several critical components into a single package. Core Function

Note: Some non-isolated variants may have different assignments. Always verify with the official Sanken datasheet for your exact revision. str-z2062 datasheet

Understanding the absolute maximum ratings prevents component failure during circuit design. Operating the IC beyond these limits will cause permanent thermal or electrical damage.
