As much so that you stop cross conduction would be a good start

Hi dear Luka. Thank you for reply.
In Ir2110 there is a delay matching circuit that compensates and equalize the total delay between High input to High output and low input to low output. and this delay is too short that can't acts as dead time. What is your offer for making an adjustable dead time circuit for a half bridge topology with IR2110? you will make me more glad if you attach a schematic to your valuable answers.
thanks
