Application Scenarios & Design Considerations

LATCHED, UNIVERSAL INPUT-VOLTAGE SWITCHES

Alternative Part Number

  • STR-A6151 --: Offline switching regulator IC in the STR-A series with similar primary-side regulation function, commonly used as a substitute in small power supplies.
  • TOP224YN --: Integrated offline switcher with comparable power range and built-in MOSFET, suitable for flyback designs replacing STR-series regulators.
  • VIPer22A --: Widely available offline PWM switcher with integrated power MOSFET, a common cross-reference for STR-type regulator ICs in low-power adapters.
  • STR81145 --: Same STR8xxxx series offline switching regulator with comparable voltage/current ratings, widely used as a direct substitute in power supply designs.
