I am implementing inverting Buck-Boost Converter in hardware as shown in the picture attached. The output of this converter is negative. so I will have an issue with its gate driver. The gate driver of high side MOSFET will face negative voltages at the source. so the gate driver that I have used IR2110 will not handle the negative voltage. Can you please suggest me the gate driver topology spacillay for inverting buck-boost converter.

This is essentially a buck supply that's being lied to about where ground is.
