Double Power Density DC/DC Transformers – EP7+/EP10+ Core Design

Pulse Electronics' EP7+ series and EP10+ series achieve significant performance enhancement by using three-dimensional finite element analysis

Image of Pulse Electronics' Double Power Density DC/DC Transformers – EP7+/EP10+ Core Design Pulse Electronics has released an improved DC/DC transformer series that maintains an industry-standard footprint but doubles the component power density to over 11 W/cm3. The EP7+ series (PA5099.XXXNL and PA5100.XXXNL) and EP10+ series (PA5130.XXXNL and PA5131.XXXNL) achieve this significant performance enhancement by using three-dimensional finite element analysis to balance the flux utilization in the core, thereby minimizing AC losses and increasing saturation currents. The series is designed for continuous mode flybacks and active clamp forwards ranging in output power from 17 W to 35 W. With multiple input voltage ranges (9 V to 57 V and 33 V to 57 V) and output voltage combinations from 3.3 V to 24 V, they are suitable for a variety of end-applications.

  • Power range:
    • PA5099.XXXNL up to 17 W
    • PA5100.XXXNL up to 27 W
    • PA5130.XXXNL up to 25 W
    • PA5131.XXXNL up to 35 W
  • Topology: forward and flyback
Applications
  • PoE and PoE+ applications
  • IP phones
  • Security cameras
  • Instrumentation/automation test equipment
  • 5G network/datacom
