BD7F100EFJ-EVK-002: Isolated ±15V @ 165mA, 24V in, Step Down Flyback

BD7F100EFJ-EVK-002 Evaluation board delivers 2 outputs, +15 volts and -15 volts from an input 24 volts using BD7F100EFJ-LB, Isolated Flyback DC/DC converter integrated circuit, with output current rating of 165mA per channel maximum.

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.
