BD7F100HFN-LB
BD7F100HFN-LB is Optocoupler-less Isolated Flyback Converter manufactured by ROHM.
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 bees 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 pensation parts bee unnecessary, therefore a highly efficient isolated type power supply application can easily be produced.
