  • Combined synchronous rectification and primary feedback control functionality
  • Wide supply voltage range (8.6 V to 38 V)
  • High level of integration, resulting in a very low external component count
  • Wide opto coupler output voltage range (3.5 V to 38 V)
  • Accurate internal voltage reference for voltage control (within 1 %)
  • High driver output voltage of 10 V to drive all MOSFET brands to the lowest RDSon
  • Low current consumption
  • High system efficiency from no load to full load
  • Undervoltage protection
  • Internal over-temperature protection

Target Applications

  • Intended for adapters and other discontinuous conduction mode systems
