Tool/software:

Dear Sir,

Please check the circuit, There is any modification needed. I took the reference from EVM board. I am getting 48-60V at Gate driver output. 

Thanks

    Ajay,

    One piece of feedback that I would have is that adding capacitors to VS and VOUT would help filter out transients and improve EMC.

    Additionally, depending on the loading requirements of the external FETs, you might want to increase the BST capacitor to something along the lines of 470nF or even 1uF. 220nF is pretty low and it is possible that your BST voltage would collapse.

    Best Regards,
    Tim
