BD7F100HFN-LB

Datasheet Optocoupler-less Isolated Flyback Converter BD7F100HFN-LB BD7F100EFJ-LB General Description This product guarantees long time supply availability in the industrial instrumentation market. BD7F100 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.
