Application Scenarios & Design Considerations

Programmable Frequency, 2A Output 30V Step-Down Switching Regulator

Alternative Part Number

  • LMR14030SDDAR --: 3A 40V synchronous step-down converter in SOIC-8 PowerPAD, similar input voltage range and current rating to the SC4524, widely available and pin-function compatible.
  • MP2359DJ-LF-Z --: 1.2A 30V step-down converter in small package, good functional substitute for low-current buck applications of the SC4524 with lower cost and good availability.
  • AP3211KTR-G1 --: 1.5A 30V asynchronous step-down converter in SOT-23-6, suitable drop-in style replacement for similar buck regulator designs with different series naming.
  • LM2596S-ADJ --: Widely available adjustable step-down regulator in a similar SOIC package, commonly used as a drop-in substitute for Semtech buck converters.
  • MP1584EN --: Compact high-efficiency buck converter with comparable input voltage range and current capability, suitable replacement in many designs.
  • AP6503 --: Integrated synchronous buck converter offering similar switching regulator function and package options for Semtech SC-series parts.
  • LM2674M-5.0 --: Pin-compatible step-down regulator with similar current rating and fixed 5V output, widely available and well documented.
