I am facing issues with the synchronous buck convert IR2104 Mosfet driver

I am building a MPPT Solar charge controller.I am facing issues with the synchronous buck convert where we used IR2104 Mostet Driver and IR540 Mosfets in the charger controller. When I connect battery to the circuit with in fraction of seconds the the low side mosfet is getting blown and making battery short circuit. Can anyone help me in solving the issue. If you want I am ready to share circuit here.

Thanks in advance.
