i used ir2110 to drive boost converter (low side switching) but when i connect the source input it make short circuit and the dc source turned off. i don' know the reason i simulate it on Proteus and it works fine.
note; i didn't find ir2110 in proteus so i used ir2112( they are the same )

I used pc power supply to source 12v,5v for the ir2110 and also as input source for the converter at 12v
 
It's clear you have limited experience in power electronics, buffer needed to supply the current peaks necessary to turn the fet on and off efficiently - also for non logic level mosfet, buffer / level shifter needed to go from 3v3/5V of the uP to the 12 or 15V needed to take the fet into fully saturated turn on
 
despues de 10 años transcurridos, debiste de haber resuelto el problema..

After 10 years, you should have solved the problem.

I guess 30 years Power Electronics experience is not enough.
