Hi support team.

Do you have the max value of CAOx source/sink current overdriven?

Hi, Daisuke

the sink/source current of CAOX in the table you shown is the current when overdriven, it could be the maximum sink/source current of CAOX. It doesn't affect the loop compensator design, CAOx transconductance affect the loop response speed.

Here is the characteristic of CAOX transconductance.

Hi Yunsheng-san

Thank you for your reply.
I understand but I can't look your suggestion regarding CAOX transconductance.
Would you please update it again.

Best regards,
