Application Scenarios & Design Considerations

INTEGRATED SWITCHER

Alternative Part Number

  • TNY276PN --: Offline switcher IC in a comparable power class with integrated MOSFET and current limit, commonly used as a functional substitute in small flyback supplies.
  • VIPER22A --: Widely available offline PWM switcher with integrated high-voltage MOSFET, suitable for low-power AC-DC adapters and often cross-referenced to Sanken STR series.
  • ICE3BR0665J --: Integrated power stage offline flyback controller with built-in protection features, a practical alternative for low-to-medium power SMPS designs.
  • STR-A6351 --: Same STR-A series offline switching regulator family with similar pinout and control scheme, commonly used as a direct substitute in low-power AC-DC supplies.
  • TNY267PN --: TinySwitch-III offline switcher offering similar power capability and simple design, suitable as a functional alternative when layout is adapted.
