Is there a voltage application order for the SHDN terminal and IN terminal on the LTC4359?

Hello,

there is no sequence mentioned in the datasheet. But keep in mind that the LTC4359 is powered via the IN pin, hence any voltage applied to SHDN before VIN is available has no effect on the part.

Have you tried Vin first first, then shdn? What happens then?

Your complete schematic and setup would be helpful/necessary for detailed support.

kind regards

Markus

Thank you for your reply.
If I apply VIN first and then set SHDN to H
It worked normally (GATE is 3V higher than OUT)

i will review the measurement conditions again.

Thank you very much.
