The PMP4468 is a DC-DC isolated module reference design targeted for industrial and telecom applications. The DC input range is 18V-36V, with 24V typical and the output is 5V/6A. An active clamp forward controller LM5025A is used in the design. The efficiency is up to 90% with good thermal performance.

  • Fully tested to comply with the industrial requirement
  • ACF converter with self-drive S.R
  • Protection feature OCP, Input UVLO
  • High Efficiency 91.3% @ 24Vin full load
  • Good thermal performance with 4-layer design
  • Small dimension: 44mm x 68mm x 10mm
