Dear Bosheng,

We appreciated your great support!

May I know why we have current limitation at 25A.

Do we have another method can meet customer spec?

Many Thanks,

Jimmy

Hi Jimmy,

To support 25A, some of the power stage components (fuse, inductor, current sense circuit) need to be changed, also the firmware needs to be changed. The original design only support 10A. Sorry I am not aware of any reference design which can meet your spec.

Regards,

Bosheng

Hi Bosheng,

If the customer makes a 10A design, can they be connected infinitely?

Many Thanks,

Jimmy

Jimmy, what do you mean "connected infinitely"?

Hi Bosheng,

If the customer makes a 10A design, can they be infinite paralleled?

Many Thanks,

Jimmy
