Dear Sir/Madam,

 

Our customer asked as following question.

 

Why does your table-18 of datasheet ADuM3471 show a coil JA4631-Bl (1:2 turns ratio) for Fig-38?

 

We will make VDD1=5V and Viso=15V.

If so, we should choice a coil JA4650-Bl(1:3 turns ratio), correct?

 

Please give me your good comment.

 

Thanks Kaos
