Hello every one, sorry for not answering for to long.
Well, my concerns is not about the totaly max current that the coil can withstand without burn out.
The IC watching the current ammount flowing throught the coil with measuring resistor, and switches ounly when it reaches itsmaximmum. So if...
About IC -s operation. In my first post I attached the datasheet for controller IC, the whole process of votage conversion is written there precisely.
But in short, in boost mode A MOSFET is always open, B MOSFET is always closed, and D-C MOSFETS switching alternately. In buck mode A and B...
Hello everyone!
First of all ishould clarifie the IC s operation. It is not buck-boost, rather buck + boost. It senses on FB pin what voltage we want from it and switches mosfets accordingly.
About inductor on input. Well, as i understand the conception of a boost curcuit, it shorts the...
Wont it decreese the ammount of current you can gain when you short the inductor?
Because if you put another inductor in serial, with same characteristics you halve the current.
But it is easy to trie out, so i'll give it a shot :)
Thanks for the help!
Yeah, may be you are right. I going to trie out to transport all the parts on the evaluation board and correct that mistake.
May be i shouldnt use the oscilate word, because according all signs the IC goes into fault and cant climb out of there(fault pin output, soft start input charges and...
Helo, thank you for your help.
About the mistake. It would be the right thing to do, but to do so i have to cut the PCB, and it is more than two layers, so it is a little bit expensive. I would rather leave this at the end.
About power loses. Yes, i would rather say the efficiency lose. In...
Hello!
I dont have to much expirience in power electronics, actualy it is my first serious project.
I have an issue with circuit, based on LT8393 buck-boost led driver IC. The design works fine (it reaches the designed 30V, 3A output (the input is 12V, ~8A)), but if a current rises up to fast...
