  • Characteristics
  • Applications
  • Comments
  • easy design in solution
  • less external components needed
  • small board space
  • low cost
  • no optocoupler needed!
  • long term reliability voltage control
  • no aging
  • same external parts for different output voltages
  • easy design of custom power supply due to standard circuit and change of transformers and two components for feedback loop
  • Isolation voltage up to 2.5 kV
  • Isolated power design
  • Sensor interfaces
  • Isolated telecom converters
  • Power over Ethernet
  • Dependant on application, the transformer specification can slightly differ to data sheet.
