I want to get rid of my battery that I use for my high side switch.
I have some 6W (bit much) murata isolated DC DC converters, and want to make a decent isolated gate driver with them:

as a opto isolater input I will use the one suggested by Matt Watts:

HCPL-2212-000E

It is crucial it can withstand the high voltage impulses created by the inductive spikes. aiming for 1700V 500nS @ 70kHz at least

as gate driver I will probably use the same as matt, the IXDD614PI

This will leave the -5V unused, but thats fine. Or there is someone who knows of a equally fast gate driver IC with +20V -5V?

the murata gives lots of noise, so I intend to use a PI filter on the output to get rid of it. this is new for me, but should be possible.

as opto isolators barely give decent info on transient (impulse) isolation values

It might be interesting to build one from a fast LED, a optical glass fiber, and a reciever with amplifier.

like musical tesla coils which are provided with a music signal by optical cable.
but then a little more refined.

this would solve all possible isolation problems on the input side.

Have you tried pcb bifilar stacked of 3?

Like to try with NR circuit
