Thank you very much for replying.
I fully understand your company does not guarantee operating current.
I could achieve <200mA at normal operating condition ( after login prompt).
But at start-up, I saw over 1A current around the following log(maybe at 7.078856 sec).
Is it possible to reduce the current at start-up?
