BD7F200EFJ-EVK-001: 4 Channel Isolated Flyback Converter, 15V @ 150mA, 24V in

Summary

The BD7F200EFJ-EVK-001 Evaluation board delivers four outputs each 15 volts from an input of 24 volts using the BD7F200EFJ-LB, Isolated Flyback DC/DC converter integrated circuit, with a maximum output current rating of 150mA.

BD7F200 is an optocoupler-less Isolated Flyback Converter integrated circuit. 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.
