Application Scenarios & Design Considerations

Two-Phase Synchronous Buck Controller w/Integrated Mosfet Drivers 32-VQFN -40 to 85

Alternative Part Number

  • LM2743MTCX/NOPB --: Synchronous buck controller with similar voltage-mode control and gate drive capability, available in a small package and widely used as a TPS40131 substitute.
  • ISL6545CBZ --: Single-phase synchronous buck PWM controller with comparable input range and MOSFET drive, suitable for similar point-of-load applications.
  • NCP1587ADR2G --: Low-cost synchronous buck controller offering similar functionality and gate drive, usable as a functional replacement with minor layout adjustments.
  • LM2743MTC/NOPB --: Synchronous buck controller with similar voltage-mode control and gate drive, available in TSSOP; a practical functional substitute when the RHB package is not required.
