Key Document


The PMP10324 sync-boost reference design provides 38V @ 2A over a wide input range covering the 24V rail. It uses dual external FETs to achieve a full load efficiency of 97% at 24Vin. This design uses minimal footprint parts with all ceramic capacitors.

  • 97% efficiency at 24Vin
  • Small size
  • Easily supports higher load transients by adding additional output capacitor (see schematic notes)
  • This reference design has been lab tested and is supported with design files and an application note
