Actually I had not seen that. I don’t have time at the moment to read it fully but have a look at this thread where I was floating the idea of a buck driver for the Q8.
Basically while possible and actually not that hard from a component / schematic layout point of view. For less then 3-5 amps it is also pretty easy to make it work.
It is quite hard on the other hand in the real world to deal with all the EMF that are emitted at high currents. 10+ Amps is something that many have tried at this point but no one has been able to make work yet.
Possible for sure but it would cost a fair amount in components and prototype PCB’s in order to get it working. If I ever have enough spare funds to take that on I plan to give it another go. Just not right now.
I already have the schematic and buck converter figured out (the datasheet has a good schematic to start from), just the components and layout that need to be figured out.
