Application Scenarios & Design Considerations

+12V/+15V Step-Up Current-Mode Pwm Regulators

Alternative Part Number

  • LT1372CS8 --: Boost/inverting switching regulator in the same class as the MAX733, with comparable input voltage range and current capability; a common second-source choice for step-up converter designs.
  • MC34063A --: Widely available general-purpose DC-DC switching regulator that can be configured as a boost converter; lower cost and broad availability make it a practical fallback when exact specs are not critical.
  • LM2577S-ADJ --: Adjustable step-up switching regulator with similar boost topology and current rating; well-documented and easy to substitute in designs originally using the MAX733.
