Design considerations

  • Point of load non-isolated DC.DC
  • Asynchronous buck converter circuit
  • Economical, two-MOSFET design
  • Standard efficiency
  • Step-down of voltage while stepping up current
  • Flexibility to replace MOSFET diode pair with LFPAK56D dual or LFPAK56D half-bridge MOSFET
