I consider using LT8709 for negative inverting converter as -48V to +12V, 3A. But I don't understand the equations in table 2 on LT8709 data sheet. Because I don't understand what the parameters mean as follows. There are 0.58, 0.05 and 1.6 in the Rsense equation, there are 12.5mV, 40mV and 3mV in the L calculation. So I'll try to calculate following AN19fc below link. What do you think abut that ?
