Optocoupler-less Isolated Flyback Converter - BD7F100EFJ-LB

This product guarantees long time supply availability in the industrial instrumentation market. BD7F100EFJ-LB is an optocoupler-less Isolated Flyback Converter. An optocoupler or the tertiary winding feedback circuit which was needed to obtain a stable output voltage isolated by a transformer in the conventional application becomes unnecessary, thus, the number of parts is reduced drastically, producing a small-sized and high-reliability application isolated type power supply. Furthermore, a highly by the use of the Original Adapted-Type ON-Time Control Technology, it makes the external phase compensation parts become unnecessary, therefore a highly efficient isolated type power supply application can easily be produced.

características:
    • 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
