Posted in the wrong thread but moved back over here (soz)
Righto this is a very preliminary look at the FlipSky 20S Anti Spark but I thought I’d share some pictures because I could take ages to give much else
Overview: (I like the bus bar for the negative)
Core power components:
MOSFETs
High Side Driver (bottom left)
Linear regulator for the circuit logic (top right-ish, square package below the bus bar and solder blob)
Disclaimer: This is only commenting on basic component choices and not the topology, and I’m not an expert. With the exception of that diode I didn’t check, they all seem to be 150V rated parts from big name manufacturers. The current ratings on the fets should be weeell within spec, if the traces are up to it they could theoretically do 676A continuous. 12AWG though lol.
If I get some inspiration I’ll check some less basic stuff like comparing it to application notes and see if that driver can match the gate charge of the 4 or whatever.
PCB:
I didn’t do a great job capturing this (and forgot to measure) but it is as advertised a big chonky aluminium PCB. This pic might be useful?
