Can you find anything wrong with this schematic?

I need to convert 48V to either 36V (19.4 up to 26.4 Amps) or 24V (10.4 to 22.1 Amps)

Thanks Andy,

But the VIN for this design tool says Vin = 8V to 36V,

Is there any reason I can't set Vin = 48 Volts?

Thanks,

Hi Craig,

The Calculator is released with design example, first you need to Enable Content as prompted by Excel, then just change the parameters in Yellow Input Box.
