Application Scenarios & Design Considerations

Wide Input (8V-40V) up to 1MHz Frequency Synchronous Buck Controller, source/sink with prebias

Alternative Part Number

  • LM2743MTCX/NOPB --: Synchronous buck controller with similar voltage-mode control and wide input range, available in TSSOP package; a close functional substitute from a different TI series.
  • ISL6545CBZ --: Single-phase synchronous buck PWM controller with comparable input voltage range and gate drive capability, suitable as a cross-vendor replacement.
  • NCP1587ADR2G --: Low-voltage synchronous buck controller offering similar functionality and package options, providing a cost-effective alternative from another manufacturer.
  • LM2743MTCX --: Synchronous buck controller with similar voltage-mode control and wide input range, suitable drop-in for many TPS40057 applications.
