I would like to build a DC-DC converter circuit using EasyEDA that can output about 80V from 7 Nissan Leaf battery modules that are about 55V nominal.
I am looking at the datasheet for the LM5164 and page 16 shows an example 12V converter with a parts list on page 17.
I don't know much about inductors; I think I get their basic principle of magnetics but I have never tried to build a functional circuit using inductors before; until now I have just used linear regulators.
The parts list says to use inductor MSS1246T-683MLB but JLC-PCB do not appear to stock this. How would I know if SWPA6045S680MT is an acceptable equivalent?
I assume that resistor RFB1 and RFB2 are generating the reference voltage that sets the output to 12V. What formula would adjust these 2 values to make the output 8V?
