Application Scenarios & Design Considerations

TPS54352/3/4/5/6/7: 4.5-V to 20-V Input, 3-A Output Synchronous PWM Switcher

Alternative Part Number

  • LM2675M-ADJ --: Simple switcher buck regulator with adjustable output in a similar power class; different series name makes it easy to distinguish, and it is a common drop-in style alternative for low-current step-down designs.
  • L5973D --: Monolithic step-down switching regulator with comparable input voltage and current capability; a different manufacturer and series provide a genuine second-source option.
  • MP1584EN --: Widely available buck converter IC with similar voltage range and load capability; different prefix and vendor make it a clearly distinguishable third alternative.
  • LT1376CS8 --: High-efficiency buck converter with comparable input voltage range and output current, suitable replacement when layout can be adjusted.
  • MC34063AP --: Versatile general-purpose DC-DC converter IC that can be configured as a buck regulator, low cost and broadly stocked as a fallback option.
