Application Scenarios & Design Considerations

Power Switching Regulator

Alternative Part Number

  • LM2575D2T-5G --: Pin-compatible step-down switching regulator in a D2PAK package with similar current rating and function; widely available and directly substitutable in most buck converter designs.
  • MC34063AP1G --: Same MC34063 family DC-DC converter controller with equivalent functionality and voltage range, available in a DIP package; a well-known drop-in style alternative from the same lineage.
  • LT1076CT --: Robust step-down switching regulator with comparable input voltage and output current capability; suitable when higher performance and reliability are required.
