Isolated Flyback Converter for Industrial Bias Supply - Reference Design


Design files


PMP7932 is an isolated flyback converter which accepts an input voltage of 12Vin to 24Vin and provides dual polarity ouputs of +12Vout @ 0.25A and -12V @ 0.25A.

  • Ease of use with off the shelf transformer
  • Internal MOSFET
  • Split rail bias supply
  • Isolated input/output for safety
  • Small solution size
  • 300kHz and 700kHz frequency options
  • Cycle-by-Cycle current limit
  • Small device package size
  • Dmax of 90%
  • Excellent line and load regulation
