18-V to 36-Vdc input, 5-V/30-W active clamp forward reference design


Design files


The PMP4468 is an isolated DC-DC module reference design targeted for industrial and telecom applications. The DC input range is from 18 V to 36 V, with a 24-V typical input and a 5-V, 6-A output. The LM5025A active clamp forward controller 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 features: overcurrent protection (OCP), input undervoltage lockout (UVLO)
  • High efficiency 91.3% at 24-VIN full load
  • Good thermal performance with 4-layer design
  • Small dimension: 44 mm × 68 mm × 10 mm
