Hi,

can you explain what this converter boas is? where it will be applied and how the power is connected?
can you sketch a block diagram showing the usecase?

Dear Steven:
Thanks for your reply. The reason is different impedance for this issue?Thanks.

Hello Jason,

as Steven said, this is not recommended for serial production.

If you are doing that for testing only then you can use it but you have to make sure that you do not create extra insertion loss and have to keep a good impedance matching for the whole system so that you do not creat more reflections.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
