18-60VDC Input Isolated Flyback Reference Design with a 54V/1.1A Output


Design files


PMP7361 is an isolated flyback converter with a 54V/1.1A output.  The 18-60VDC input is suitable for 24VDC industrial and 48VDC telecom applications.  The 54VDC output can be used to power PoE power sourcing equipment (PSE).

  • Efficiency of 93% with 48V input and maximum load
  • Good line/load regulation with optocoupler feedback
  • Wide input range
  • 1500Vrms isolation for telecom or PoE
  • Optional capacitors to provide hold up time
