Application Scenarios & Design Considerations

POWER SUPPLY OUTPUT SUPERVISORY CIRCUIT

Alternative Part Number

  • UC2543N --: Pin-compatible industry-standard equivalent of the SG2543 series, widely available and well documented.
  • MC2543N --: Same 2543-series function and pinout, direct drop-in replacement for the SG2543N.
  • CA2543E --: Equivalent 2543-series controller in DIP package, suitable functional substitute.
  • SG3524N --: Classic regulating pulse-width modulator in DIP-16 with similar control architecture, commonly used as a functional substitute in power supply designs.
  • TL494CN --: Very common PWM control IC with comparable oscillator, reference and dual output stages, suitable as a design alternative with minor circuit adjustment.
