TPS92630-Q1 / Vsns resister value

Guru 20090 points
Hello,

Vsns R15,R18 resister values are difference between user's guide and evm.
R15, R18
EVM: 25.5kohms
User's Guide: 51.1kohms
 
Could you please let me know this reason?
Best Regards,
Ryuji Asaka
  • Hi Ryuji,

    R15 and R18 are used to configure the Short-Circuit Detection. On the EVM, 25.5kohm R15 and R18 are set to detect two LED shorts on the output. In the user's guide, 51.1kohm resistors stand for one LED short detection.

    The reason why the value of  two resistors are different may be negligence on the documentation. I'll discuss with our engineer to fix this problem. Thank you for your comment.
