    Hello everyone,
    I am planning to use the IR2110 high side and low side gate driver.
    As per the data sheet ,attached image below:

    Am i right in assuming that the "Delay matching" is the dead time delay which is set by the driver between the High and Low side gate driver output,by default?

    Also if i set a dead time(a positive dead time delay) say for example: 20ns and feed my PWM signals to the IR2110 inputs,would the resulting dead time be 30ns or 10ns?

    PLease Help,
    Arun

    Edit:
    The IR2110 is switching two IRFP4768PbF Mosfets ,configured in an half bridge configuration.
    As per the mosfets datasheet the Mosfet off time is 57 ns,so shouldn't my dead time be more than 57ns?
