PTN78020H: Parallel design with LM5050-1 ORing

Part Number: PTN78020H
Other Parts Discussed in Thread: LM5050-1,

Hello,

I'm designing a board for hydrogen fuel stack application in automotive industry.

I would like to know if I can use two DC/DC converters PTN78020H in parallel if I protect each of them with OR-ing diodes like {LM5050-1 N-FET}.

Otherwise, my design would put in parallel a PTN78020H module with a 12V battery for a short amount of time (also with diode protection), do you think it could damage the module ?

Thank you for your help.

Best regards,

Adrien

    The PTN78020H devices cannot be paralleled for increased current.
    Diode OR-ing will protect the device from sinking current from another source.
    Please contact me directly at jarrigo@ti.com with any questions. I would like ot understand the specifics of your application.
