Application Scenarios & Design Considerations

Three-terminal Off-line PWM Switch

Alternative Part Number

  • TOP221Y --: Same TOPSwitch-II family with identical pinout and control scheme; lower power rating but a direct functional substitute for many TOP104 applications.
  • TOP100Y --: Original TOPSwitch family member in the same Y package with comparable voltage and current ratings, suitable as a drop-in replacement in most designs.
  • VIPer22A --: Off-line PWM switcher with integrated high-voltage MOSFET, widely used as a cross-family alternative to TOPSwitch devices in low-power supplies.
  • NCP1014AP065G --: Integrated offline switcher with built-in MOSFET, similar power range and TO-220 style package, commonly used as a direct functional replacement for TOP-series offline switchers.
  • LNK304PN --: LinkSwitch-TN family offline switcher from the same vendor ecosystem, suitable for low-power non-isolated supplies and a practical cross-series alternative.
