DA9073 - question / issue

Dear all,

I have question for you about DA9073:

Currently in our solution we supply DA9073 from 3.6 V. I did tests of DA9073 evaluation board (320-30-A) with wider range of input supplies and different loads (resistance load). I have results as in attachment.

And I saw in your datasheet:

SCP threshold for higher Vout range --> typ. 4V

In my knowledge SCP is Short-Circuit Protection,does it mean the same in your specs? Does it mean that below 4 V input we cannot have 10V from Boost Converter?(the results looks like this… we have UVLO flag and don’t have “output” when load is “bigger”)

Thanks!

Hello,

Hello,

I believe my colleague is looking into this. I have attached two figures from the datasheet that might be use to you. Figure 13: Boost Maximum load capabilities and Figure 41: Maximum load at start-up.

Kind regards,

ED

Hi,

Hi,

Yes, I saw this pictures. But I found first issue with load 125R (it's about 80mA), so it should work according to these pictures..

Kind regards,

Monika
