Would this circuit work? I am using a 555 timer to generate the frequency of need and then use a mosfet driver max4420 to drive the Mosfet.
What would be an issue with this circuit.
Do I have to protect Mosfet against high voltage if I have an inductor on drain side or source side (between Rd and Mosfet) or against parasitic inductance?
I would like to keep IRFP running below 40C (may need heat sink). Any suggested max current/voltage limitation? Varaible resistor should accomplish the desired current for maximum efficiency.
What transistor would be adequate for this circuit?
How do we choose which Diode is best suited (I beleive this is dependent on driving current and 1N4148 can be used up to 150MA and BAS40 up to 300MA)
I was hoping to use this circuit as a frequency generator for various voltages/currents and wanted it to be fast turn on/off times hence the mosfet. Rd is only there to control current and is not the load.
I am newbie in electronics and am trying to learn. Any advice is appreciated.
