LM5035x EVM

Guru 29710 points
Other Parts Discussed in Thread: LM5035C, LM5035B, LM5025C, LM5025B, LM5025A

Hi Team,

Is seems there is only LM5035C EVM in website for LM5035x series.
Should my customer make replacement the IC on EVM if he wants to evaluate LM5035A or LM5035B?

Best Regards,
Yaita

  • Kensuke-san,

    Since my colleague Oliver is already verifying the answer to your other posts about LM5025A & LM5025B using the LM5025C EVM, we will be able to answer this question also.

    We will post the replies when we have the verified results. This will take a few days longer, since we are waiting for IC samples to be delivered.

    Thanks,
    Bernard
  • Bernard-san,

    I really appreciated for your team's support.
    I understood.
    I will wait for your team's feedback.

  • Hi KENSUKE-San,

    For LM5035A/B, the SR1/2 output high voltage(VOH) is VCC which is exceed the ABS of isolator(while for LM5035C it is VREF), so you may need to add a divider between SR1/SR2 and the isolator inputs(A1/A2) to bring down the VOH to compatible with LM5035A/B.
    We recommend LM5035C since the amplitude of SR gate drive reduction make it compatible with isolator used for secondary synchronous rectifier's control. In addition, the removal of soft stop make the power-off duration more reliable than the other version.

    Best Regards

  • Hi Oliver-san,

    Thank you for your reply.
    Is there LM5035AEVM and LM5035BEVM?
    My customer also wants to evaluate LM5035A and LM5035B.

  • Hi KENSUKE-San,

    Sorry, we don't have EVM for LM5035A or LM5035B.
