Dear all

I'm Narisawa who is distributor FAE in TI division .

I have some questions as below. 

Q1.Customer needs regulation value like below.(TLV62090)

 Do you have any similar data as reference?

  Q2.Customer needs Vfb accuracy in Eco-Mode like below.

.

Do you also have any similar data. Customer wants to know Vfb variation in eco-mode.

Thank you for your kindness.

Best Regards

K.Narisawa

    Typical load and line regulation are shown in figures 4 and 5 in the datasheet.  We only list the VFB voltage as typical for eco-mode.  As you can see from fig 4, the load regulation is worse in eco-mode so I don't think the VFB voltage is relevant as a performance indicator during eco-mode.
