BD7F100HFN-EVK-001: 5V @ 800mA, 24VDC in

Summary

BD7F100HFN-EVK-001 Evaluation Board outputs 5.0V voltage from 24V input using IC BD7F100HFN, an isolated DC/DC converter. It supplies 800mA output current at 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.
