特点:
    • 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)
