Dear Specialists,
My customer is considering power circuit and has a question.
I would be grateful if you could advise.

I am considering a circuit that outputs 12V at 12V/24V input.
Could you please see attached file.
At 24V input, step down to 12 V with LM25116.
When 12V input, it is supplied to the output through the bypass line.
At this time, power from the bypass line is input to the output (12V) of the LM25116
The reverse current prevention diode is not connected.
In the condition when LM25116 is turned on the input 12V and the output is 12V from bypass line.
(1) How does the circuit behave?
(2) Is there a possibility of damage?
(3) Is there any problem?

I appreciate your great help in advance.
Best regards,
Shinichi
