Wire-Wound Transformers Provide Regulation And Isolation

Pulse Electronics’ PA4470.XXXNL high-frequency, wire-wound transformers are low-power components for use in a discontinuous mode flyback circuit that provides both the regulation and the isolation required for datacom and industrial applications. They are viable for low-power isolated designs where 3.3V, 5V, and 12V is needed to be converted from 24V or 48V bus architectures. Features include:

  • ER7.5 8-Pin SMD platform
  • Power Range: Up to 1.8 W
  • Topology: Flyback
  • Isolation Voltage: 1650 Vdc
  • Easy design-in solution
  • Small board space
  • Low cost
  • No optocoupler needed


Applications include:
