Four-Output, Flybuck and Buck Converter for High Performance Computing Reference Design


Design files


The PMP10837 reference design offers dual output rails for use in enterprise computing.  This design implements an isolated step down design, with non-isolated converters on both the primary and secondary side.

  • Small Board Size
  • Good thermal performance (Max of 60 deg C)
  • Over 80% efficiency when both primary and secondary sides are enabled
  • No external compensation allows for easy design
