Does LP# pin input will affect normal full load operation?

(i.e. Can I GND connected to LP# for full load operation)

The LP pin is intended to be actively pulled low by the system during standby operation. I am not sure what the effect of pulling it low during full load operation will be. It may take some time to get an answer, maybe one week.

Thanks for your reply. If then, I will add default pull up & option pull low resistors for make sure can operate in normal full load operation.

Hey guys,

Any update on the function of the LP# pin? I'm in the midst of a design review and need a little more information. Can I leave this pin floating? Should I pull it up to a given voltage?

It is just used to put the device into ultra low power mode. If you leave it floating it will always be in normal operation.
