Hi.
Perhaps this will interest all noobs like me that like to read ? If not it can be deletet.
I know the basics about elektronics but have not been doing mutch since 1979 so many things are new to mee.

I really like all the hints and information that can be found in this forum, and after reading a little about buck/boost I was wondering if I could be making one by myself, so I started google
Around and found some interesting tips on a Swedish forum, and they mentioned TPS63020, I remembered reading about it in something written by “foulmist”.
There was a link to Texas Instruments, so I could read some specifications
DC/DC Converter (Integrated Switch) - Buck-Boost Regulator - TPS63020 - TI.com

3A sounds good enough for me
Further down on the page there was something with input boxes and it sad
“Design Now with SwitcherPro”
I tried to fill in some numbers but I had to be a registered user.
Naturally I registered myself and after some more clicking with my mouse I found TPC63020 again.
Now I could choose to create a new design with this circuit so I did.
I filled in Vin (min/max), Vout, Iout, Vripple and the tool gave me things like
Schematic, Layout, Component list and so on
( Please see the attachments below )
I could also order the components if I understood everything right.
I hope this info is useful for someone out there.
I guess that the board design easily could be changed to dubbelsided and perhaps even two boards above each other if it will make it smaller.

Now a question from a noob!
I read something about that the normal low voltage protection on TPS63020
might damage the batteries, can this not be fixed by putting a diode in
series with batteri and the circuit? And fool the protection so the batteri has 1 voltage more left ?

Nobody that has an opinion? Can I use the info from the tool to build a circuit?
Can I use a diod in series with the battery to save the battery?
 
That's not going to work as you are voltage regulating instead of current regulating.

If the website was going to spit out designs for a perfect boost driver we would have made them ages ago ;)

Have a look at this thread...

If it looks to god to be true....
Tanks Benmwv and Lasersbe, I will look on the DIY project .
