Typical electrical specifications (from datasheet)

• Input voltage range: Designed for universal AC mains (approx. 85–265 VAC).
• Switching frequency: Manufacturer-specified nominal switching frequency and tolerance, often tens to hundreds of kHz.
• Maximum drain/source (or collector/emitter) voltage/current: Peak ratings for the internal transistor allowing safe design margins.
• Quiescent current / standby power: Important for meeting low-power standby targets.
• Protection thresholds: Current limit, overvoltage detection, and thermal shutdown setpoints and behaviors.

The STR-Z2062 integrates a power MOSFET, a quasi-resonant controller, and protections in a single package. It operates by controlling the switching of the MOSFET to regulate the output voltage. The quasi-resonant operation allows the converter to achieve high efficiency by minimizing switching losses. The STR-Z2062 is a specialized Pulse Width Modulation
