PMP4394 is a 24Vin, +/-5V, 1W reference design which is implemented in the standard industrial SIP pinout.  It includes a constant on-time synchronous Fly-Buck controller LM25018.  The solution has high efficiency, good line, load regulation with 1500V DC isolation.  The power module has been designed with minimized component numbers for cost sensitive applications.  PMP4394, PMP4401, and PMP4412-PM4415 have the same pinout and can be replaced by each other without modification.  The 24V input capability and isolated outputs make the series ideal for industrial applications.

  • Fly-Buck topology with 1500Vdc isolation
  • High efficiency
  • Good line and load regulation
  • Low cost solution with minimized component count
  • Industrial standard pinout
  • Size: 19.8mm x 9mm x 5.8mm
