I hooked up an lm2596 DC-DC buck converter to a gate drive optocoupler i have, then hooked the output of this up to the gate of my mosfet.
I switched the gate voltage on and the the mosfet conducted for maybe half a second before shutting off.
I have tested the fet and it is fine, but my LM2596 is no longer working.
I thought maybe the inrush current from the gate capacitance surpassed the 2A rating and caused the failure.
The gate capacitance is 210nF and i did not use any gate resistors.
I have ordered more converters, but until they arrive. I need to ensure i don't let this happen again.
Both my pocked and my watch are getting irritated with my tendency for wastage.
