Features

  • Supplies three isolated outputs, each 9 V, 50 mA from single 9-V source
  • Coreless transformer cannot saturate because of external static magnetic field
  • Low input-output inter-winding capacitance thanks to resonant topology
  • Open loop converter: no feedback compensation
  • Possibility to use coreless transformer or printed windings on the PCB
