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.
