Application Scenarios & Design Considerations

Synchronous Buck Controller for Dynamic Load-Voltage Applications

Alternative Part Number

  • LM3478MM --: Widely available low-side N-channel controller in MSOP-8 that can serve as a functional substitute for the SC470 boost controller in many designs.
  • TPS40210DGQ --: Versatile wide-input boost/SEPIC controller in MSOP package with adjustable frequency, offering similar control functionality and good availability.
  • LT1932ES6 --: Compact boost converter IC in SOT-23 that provides a comparable step-up regulation function for lower-power applications.
  • TPS54202DDCR --: Wide-input synchronous buck converter with integrated switches, similar step-down function and compact package, easy to source and well documented.
  • MP2315GJ-Z --: High-efficiency synchronous step-down converter in a small package, comparable current capability and pin-friendly layout for power supply designs.
  • AP3211KTR-G1 --: Low-cost synchronous buck regulator with similar input voltage range and output current, suitable drop-in style replacement for general power conversion.
  • UC3843AN --: Classic current-mode PWM controller with broad availability and well-understood compensation, usable as a lower-cost alternative where the integrated switch is not required.
