REFACDC033 - Reference Design

Isolation Fly-back Converter Quasi-Resonant method Output 24 W 24 V

BD7682FJ-LB-EVK-402 evaluation board outputs 24 V voltage from the input of 300 Vdc to 900 Vdc. The output current supplies up to 1 A. The BD768xFJ-LB series are Quasi-Resonant switching AC/DC converter for driving SiC (Silicon Carbide) MOSFET.


  • Using external switching MOSFET and current detection resistors provides a lot of flexibility in the design.
  • Power efficiency is improved by the burst function and the reduction of switching frequency under light load conditions.
  • This is the product that guarantees long time support in the Industrial market.
