Thanks for the reply,is there any other alternative to this(bootstrap caps)?I read somewhere we can use isolated dc/dc converters to drive the high side fet,or some kind of pulse transformers.That circuit won't work unless the 12V is referenced to the source of the MOSFET.
That would likely require some sort of bootstrap circuit which you are trying to avoid.
R1 should be small (10-50Ω) and R2 is not needed.
You need a resistor in series with the input to limit the diode current.
