Part Number: TPS51206

Hello.

Is it OK that High-input-signal of S3 and S5 is 3.3V through resistance?

VDD is 3.3V.
VDDQ is 1.5V.

Hello everyone.
Would you be able to help me?

Is it no problem that I use resistors to S3 and S5?

If "Non-Isolated DC/DC Forum" is not appropriate for TPS51206, please move this post to an appropriate forum.

Hello everyone.

I read this article.
e2e.ti.com/.../167353

Therefore, I think it is no problem that High-input-signal of S3 and S5 is 3.3V through resistor.

Would you be able to give me comment?

Hi Dice,

It is fine to pull S3 and S5 high through resistor.

Thanks
