Hi team,

My customer is considering to use TPS61089.

Could you let me know the recommended COMP constants for configuration below?

Best regards,

Hi Kazuki,

Thank you for reaching out.

I think it is ok to use EVM's parameters: Comp=17.4k ,Ccomp=4.7nF.

It is recommended to apply for an EVM to have a test.

Hi team,

Is it okay to use Rcomp=18kOhm from E12 series?
My customer is concerned that if 17.4kOhm is important, 15k + 2.4k should be needed.

Hi Kazuki,

It will be ok to use 18k resistor.
