This information is based on the manufacturer's datasheet and product documentation.

Application Scenarios & Design Considerations

Wide Input Voltage Range, 8Amp 300kHz, Buck Regulator

Alternative Part Number

  • TPS5450DDA --: Widely available 5A step-down converter in an SOIC-PowerPAD package with similar input voltage range and current capability, making it a strong functional substitute.
  • LM2678S-ADJ --: 5A adjustable buck regulator in TO-263 with comparable voltage and current ratings, well established and easy to source as a drop-in style replacement.
  • MC34063ADR2G --: Versatile general-purpose DC-DC switching regulator usable in buck configurations, inexpensive and broadly stocked, suitable when exact current rating is not critical.
  • TPS54560DDAR --: Wide-input 60V, 5A step-down converter in SOIC-8 PowerPAD, similar buck regulator function and ratings to the SP7655.
  • MP1584EN --: Compact 3A step-down converter with wide input range, suitable lower-current substitute when 5A is not required.
  • LTC3605EUF#PBF --: Monolithic synchronous step-down regulator with similar input voltage range and current capability, pin-compatible footprint in QFN, and widely available as a direct functional replacement.
  • TPS54620RHLR --: 6A synchronous buck converter with comparable switching frequency and voltage ratings, well-documented reference design, and easy drop-in substitution for the SP7655ER-L in most power supply designs.
  • ISL85415FRZ --: Wide-input synchronous buck regulator offering similar output current and efficiency, with an integrated MOSFET design that matches the SP7655ER-L application requirements.
