    Hi HS,

    I don't think our group (WVB) has anything to meet these requirements: adj current limit; two switch forward topology, Galv iso.  You also did not mention the power level.  Let me forward this to HPC group.

    Thanks,

    Youhao

    Hi Youhao,

    a solution with an external FET is also accepted.

    Youhao,

    You can find the device that fits your specifications here. Once you select the topology desired, you can filter by features and select Adjustable current limit. Same for the other parameters.

    Thank you

    Hi Manuel,

    Thank you but I just don't know which one is suitable. We are in the WVB product line and we are not familiar with the isolated power except for the flyback.  We do have LM518x to implement a PSR flyback to produce isolated output, but they do not have adj current limit nor it support two switch forward.  

    Note that the thread has LM5015 in the subject line so it came to our attention. However, our product line do not have a part to meet the requirement. The LM5015 is a two switch forward converter but it does not have adj current limit either.  This is why I forward it to HVC's attention, hoping they may have something to support.  Let's wait for their comments.

    Regards,

    Youhao
