Features

  • Wide input voltage range (default 20V to 60V, extendable 6V to 90V)
  • Tight voltage regulation of the isolated output without opto-coupler: 16.4V ±1.5%
  • Removal of the opto-coupler and transformer aux winding saves solution size and cost.
  • Peak conversion efficiency > 90%
  • Programmable loop compensation, current limit, input UVLO, and thermal compensation allowing for flexible and optimal designs.
