Application Scenarios & Design Considerations

Switching Voltage Regulator

Alternative Part Number

  • MC34063AP --: Widely used switching regulator IC with similar voltage-mode control function; pin-compatible in many TL497 boost/buck designs and readily available.
  • LM2575T-ADJ --: Adjustable step-down switching regulator from a different TI series; suitable replacement when the TL497 is used in buck converter applications.
  • MC33063AP --: General-purpose DC-DC converter IC functionally comparable to the TL497, offering flexible step-up/step-down/inverting configurations.
