    i am making a conventional ZVS buck convertor with following specifications...
    Vin=19V; I=2 A ; Vo=13V; switching frequency= 18kHz.

    i am using IRFZ44N N-channel MOSFET for switching...

    i have only IR2110 mosfet driver available with me.....

    i need to know if its OK to use this driver for switching high side mosfet IRF Z44N for my DC-DC convertor as the mosfet driver has Io(min)= 2A. i want to know if the mosfet driver will use current from source to driver IRFZ44n thus hampering the working of convertor.

    the link below gives the datasheet of IR2110

    also i need to know how mosfet driver develops/generates current to drive mosfet, plz explain in detail???

    The gate driver gets its current from the 'logic' side of the converter, so it won't affect the converter out put. Here is a link to using gate drivers -

    The mosfet source is just connected to the driver to supply a 'reference' voltage to the bootstrap capacitor of the driver.
