Part Number: TPS23755

Hi  Bu:

Could you please help check the attached transformer is appropriate to work with TPS23755 ? Is there any special requirement of the transformer?

  • Hi Jason,

     

    The transformer is the most critical component of the DC-DC. I recommend to use the exact transformer used in the EVM/reference design. Otherwise, much of the design will need to be re-calculated. This is because PSR regulation is highly dependent on the way the transformer layers are stacked and wound. These are typically not shown in the spec sheet, so even if the transformer is “exactly the same” I cannot guarantee it will work.

     

    If customer has a preferred transformer vendor, I have found that a good approach is to provide our transformer stack-up recipe to the transformer vendor so they can design an identical transformer. I will send you an e-mail with our transformer stack-up recipe for you to share. Thanks!
