Hi !

I read the datasheet carefully.

I think PDISS_IC has to be 1 / 2.

P = QVF means one period.

Also the datasheet says we have to calculate PDISS_IC by adding RDSON_P and RDSON_N .

=> this means calculate one period

I think that this is wrong because these are duplicate to calculate one period.

I think that the correct answer is as follows, so can you check about it?

And this problem is critical technical problem and also critical problem for the schedule.

Few customers are designing there circuit and they are trying to judge to use ADUM3223 or ADUM4223.

The key point is power consumption.

So , it will help our customers and us if you can give me this answer as soon as possible.

One of our customers want to know this till Thursday.

Best regards.

Hello Kawa,

Yes, there should be a factor of 1/2 as you have noted. There is an error in the datasheet. I will arrange for a revision to the ADuM3223 datasheet.

Thanks,
