TPS61253 1A continously at 4.5V<Vin<5.5V

Hi, Chris

When I replied our conversation, It is disappeared. So. I made new conversation.

Anyway....

Question 1:
Finally I want to know that is it OK 1A continuously at 4.5V<Vin<5.5V without thermal fault
When I designed with recommended condition in the datasheet?

Question 2 :

And is it OK 1A continuously at 4.5V<Vin<5.5V without thermal fault in the Evaluation board?
In the datasheet, It seem to be OK. But it’s not plotted. <Refer to the below>

    I addressed this question in your other thread:

    Yes, the part can support 1A current as shown by the efficiency figures in the datasheet and figure 15.  A thermal fault is only a concern if you do a poor layout.  By copying the layout of the EVM, which s also shown in the datasheet, you can avoid this from happening.
