Part Number: LM25184

Hi team,

My customer uses the ZA9671-BED of coilcraft to design the 5V output of LM25184.

Basically, if want to design 2 different grounds of 5V. I can use pin5 and 7 as one of the 5V. pin6 and 8 as another one .right?

    HI Jimmy

    For the Transformer, I think it's meant to provide one output----pin7-8,pin5-6 are meant to connect together.

    If customer want to design 2 different grounds of 5V, They can choose transformer with 3 turns. 

    By the way, The quick Calculation tools on ti.com are helpful for the Lm and turns ratio selection during design procedure.

    Thank you.
