TPS23758EVM-080: Mismatch between user guide and EVM in TPS23758EVM-080

Part Number: TPS23758EVM-080

Hi Sir,

 My customer want to use TPS23758EVM-080 to build up their design. But we find some mismatch between board and user guide circuit including CLS and other components.

1. Is it correct about CLS pin floating on user guide?

2. Would you please helping to provide latest evm circuit and gerber for our reference, or SLVC777 (gerber file) and user guide (SLVUBO2B) are correct for design?

 Thanks for your kindly help.

  • Hey Gary, 

    The CLS resistor should be there. Per the note in the datasheet, the only change to the newest EVM is adding the Vb zener diode. 

    If you can accept my connect request i can send you the latest files in private messenger.  

    If this post answers your question, please indicate so by marking this thread as resolved. Thank you.
