Application Scenarios & Design Considerations

5 BIT PROGRAMMABLE STEP DOWN CONTROLLER WITH SYNCHRONOUS RECTIFICATION

Alternative Part Number

  • ISL6520ACBZ --: Single-phase synchronous buck PWM controller with similar function and pinout, widely available and a common drop-in for ST L6911 designs.
  • NCP1587ADR2G --: Synchronous buck controller with comparable voltage-mode control and gate drive, suitable replacement with minor layout review.
  • TPS51116PWP --: Integrated synchronous buck controller for DDR/VRM rails offering similar control features; requires checking compensation network but electrically compatible.
  • AP2004SG-13 --: Synchronous buck PWM controller offering comparable voltage-mode control and gate drive, suitable for similar DC-DC converter designs.
