Hi there
I am trying to build this flyback driver to creat audio modulation **broken link removed**
The problem is that everyone is complaining about the IRF540 MOSFET getting too hot and blowing. Im pretty sure its due to the ic only putting out 200ma max to the MOSFET and the MOSFET is getting "under run" causing it to heat up and blow.
Any ideas on how to fix this?
Some ideas were putting the mosfet and heatsink in baby oil (Mineral oil with fragrence, its non-conductive and supposively can help absorb the heat)
Or
Placing two MOSFET's in parrelle to increase the current (Not sure if it will work because ic max amp out is 200ma)
or
wondering is thier any other MOSFET with fast switching, can be run off 200ma, can withstand under 50v at couple amps and back emf?
thanks
