功能:

  • Guaranteed long time supply availability for Industrial Applications.
  • No need for an optocoupler or a transformer tertiary winding.
    The output voltage can be set by two external resistors and the transformer turns ratio.
  • Uses Original Adapted Type ON-Time Control Technology.
    High-speed load response is realized and external phase compensation parts are unnecessary.
  • Fixed switching frequency and low output ripple
  • Highly efficient light load mode available (PFM operation)
  • Shutdown / Enable Control
  • Built-in N-Channel MOSFET
  • Soft start function
  • Output load compensation function
  • Protection functions:
    VIN Under Voltage Lock-Out (VIN UVLO)
    Over Current Protection (OCP)
    Thermal Shutdown Protection (TSD)
