Application Scenarios & Design Considerations

Q1

Alternative Part Number

  • LM2678S-ADJ --: Wide-input adjustable step-down regulator with similar current capability, different series name, and easy drop-in for many TPS54310 designs.
  • L5973D --: Adjustable buck converter with comparable voltage and current ratings, different manufacturer and series, suitable as a functional replacement.
  • MP1584EN --: Compact adjustable step-down converter with similar input range and output current, different naming and series, good cost-effective alternative.
