Application Scenarios & Design Considerations

3A, Step-Up/Down/Inverting Switching Regulator

Alternative Part Number

  • LM2576T-5.0 --: Widely used 3A step-down switching regulator in TO-220, functionally similar to the MC33166 buck converter and easy to source.
  • LM2596T-5.0 --: 3A step-down regulator with similar input range and TO-220 package, a common drop-in style replacement for MC33166 applications.
  • L4960 --: 2.5A step-down switching regulator in a similar power package, suitable as an alternative buck converter for lower-current designs.
  • MC34063A --: Versatile DC-DC switching regulator in DIP-8/TO-220 that can be configured as a buck converter, useful when the exact MC33166 is unavailable.
