Application Scenarios & Design Considerations

DDR Memory Power Supply Controller

Alternative Part Number

  • TPS5430DDA --: Widely available step-down converter in the same power class, easy drop-in for many Semtech SC1480 designs with similar input/output ratings.
  • LM2596S-ADJ --: Mature adjustable buck regulator with comparable current capability and simple external component requirements, good second-source option.
  • MP1584EN --: Compact high-efficiency buck converter suitable as a functional replacement where board space is limited and lower current is acceptable.
  • LM3478MM --: Widely available low-side N-channel MOSFET boost/SEPIC controller with similar current-mode control function and pin-compatible layout in MSOP-8.
  • NCP3063DR2G --: Versatile boost/buck/inverting switching regulator controller that can serve as a functional substitute in similar power supply designs.
  • MC34063ACD --: Classic general-purpose DC-DC switching controller covering boost, buck and inverting topologies, useful as a low-cost fallback alternative.
