LM5116: Output current MAX value

Part Number: LM5116

Hello Team,

As I know, Buck controller doesn't matter of output current value. however, I can see Iout Max value on "Product details" on ti.com.

What is the meaning of Iout MAX on Buck controller? It is because some other device has more than 100A.

    Hello Ken 

    It is the maximum "recommended" output current which customers can achieve without a trouble (based on signal versus noise ratio).

    If the sense resistor value is too small, the amount of switching_noise / ground_offset / sense_resistor_inaccuracy might be relatively too much, and they will distort the current sense input too much.
