Query about Current Surge on ADL5611 During Power-up

Hi, there

 

I am using the ADL5611 Eval Bd. & we noticed a high initial surge current of 220mA being drawn upon power-up. Then it drops to steady current of 94mA. There is no mention of this surge current at all in the datasheet. We’re wondering whether is this the normal behaviour of the ADL5611 or is there some abnormalities. We might need to re-allocate our power-budget because of this. Can you check with it?

 

Thanks so much!

Wayne
