LTC3785 for high current applications upto 20A

Category: Datasheet/Specs
Product Number: LTC3785

Hello,

I am exploring the buck-boost converter with external switches which can accept single Li-ion battery input and generate 3.3V at 20A. I could see LTC3785 which can be used for my application, but in the datasheet it is mentioned as 10A is the max current. If we size the MOSFETs, can we use this IC upto 20A output current application?

If i want to use the external current sense resistor, please provide a sketch where it should be connected. Thanks.
