Hello,
another day another issue.
I am forced to run a wire from a mosfet driver to a mosfet.
The distance from the driver to the fet is around 80mm.
The enviorment is extremly noisy, probing the gate and the output of the driver prooved that the noise gets picked up at the wire.
I am also really space limited so the smaller the better...
I came across these small coaxial cables, I'm interested in the 90mm one:
coaxThe core wire seems to be 0.2mm (32AWG)
No idea what the conductor material is but 2Ohm seems really high for 9cm.
The mosfets I am driving are
CSD19535KCS
The drivers I am using are
UCC27511A:
Probing a 100mOhm resistor in series with the gate of a fet showed a pek current flow of around 2A.
The frequencys range from dc up to around 400KHz.
Some are fixed at aound 16% duty cycle and others are variable from 0 to 100%
What issues will I encounter using these coax's as the transmission lines?
I know the cable will see that peak current only for a short amount of time, but the insulation is very thick compared to the conducter.
Should I be worried about melting/softening insulation? (I have no clue what the insulatin is made out of.)
What traps are there I might fall into?
Are there any better options without paying with my organs?
I need to route 16 cables from 16 drivers to 16 fets...
Thanks in advance.
