Original question:

LM5000: /SHDN pin's internal circuit.

LM5000: LM5000: What is the operation when /SHDN pin is set to "H"?

Hi,

 I wants to control LM5000-3 device using /SHDN pin from MCU.

The IO pin of the microcomputer and the SHDN pin of LM5000 are connected.
When operating the LM5000, I plan to set the IO pin of the microcomputer to "OPEN" and to set it to output "L" when shutting down.
However, I think that when "Open" is set, the wiring floats and it is more susceptible to noise.
So, I want to set the microcomputer setting to "H" output instead of "OPEN" when operating it.
Does "LM5000 operate with "H" output?
Best regards,
K.Shibahara
