High Density Isolated 18-60Vin 5V 2.5A Flyback Using Standard PoE Transformer Reference Design


Design files


PMP11012 is a fully isolated 5V at up to 2.5A delivered from a wide 18 -60 VDC input range. The PMP11012 design is complete on 2 layer PCB, all parts on one side and with no forced air needed. Transformer is standard off the shelf 13 W POE type. Design includes schematic, BOM and layout Gerbers and is well supported with a detail Test report.

  • Full input to output isolation
  • Discontinuous mode flyback with standard POE transformer
  • Very wide input range of 18V to 60V
  • Thermal performance without fan well documented
  • 2 layer PCB with all parts on same side for cost sensitive applications
  • Schematic, BOM, layout and Test Report focusing on thermal performance & efficiency
