Application Scenarios & Design Considerations

5 Bit Programmable Synchronous Buck Controller IC in a 20-Pin SOIC(WB) package

Alternative Part Number

  • ISL6520ACBZ --: Single-phase synchronous buck PWM controller in SOIC-8, functionally similar to the IRU3011 controller and widely available as a direct design substitute.
  • AP3585MP --: Synchronous buck controller with comparable voltage-mode control and gate drive, suitable for replacing the IRU3011 in DC-DC regulator designs.
  • NCP1587ADR2G --: Low-cost single-phase synchronous buck controller with similar input range and feedback architecture, usable as a drop-in alternative with minor layout checks.
  • TPS51116PWPR --: Complete DDR/synchronous buck controller with integrated MOSFET drivers, comparable control and drive capability, good second-source option with broad availability.
  • NCP5212AMNTXG --: Single-phase synchronous buck controller with integrated drivers in a compact package, suitable as a lower-cost alternative for similar point-of-load regulation applications.
