How to identify SMD components?
I think, the SMDs in the pictures are:

&quot;DZAA XVFH&quot; : ISL80102/ISL80103 datasheet
&quot;1H1H 788 A5DS&quot; : ISL80102/ISL80103 datasheet

About, How I find the smd component? I usually try each group of the name plus &quot;datasheet&quot; and if I don't find anything, I may add some description word. For example:

For the first one I just googled for: &quot;DZAA datasheet&quot;
However, the second one was not that easy, I tried &quot;1H1H datasheet&quot;, &quot;788 datasheet&quot;,... Until I tried &quot;1H1H datasheet IC&quot;.

The way to check that you were correct is mainly check the pinout, and the &quot;marking&quot; section in the datasheets. In the DZAA, for example, the pinout have double Vin and Vout pins, and in the image, they are soldered together, so I can be pretty sure, it is the correct datasheet.
O hope this have been helpful.
