I see that the input current limit is stated as "about" 1.5A, based on some sort of "internal switch current limit". I assume that this internal switch is the IC that does the constant current regulation?
Post #10 in this link says that if you load a Badboy such that the board needs more than Iin,max (i.e., the input current limit) to deliver the power being demanded by the load, the board will deliver only as much power as it can up to its input current limit. It is also stated that you might get lucky and the board's Iin,max could be a little higher than 1.5A.
In the example given in Post #10 in the link above, is there any reason to spec out a Badboy 400 instead of a BB 750 (assuming that both boards have a max input current of 1.5A)? Is there any risk of overtaxing the BB 750 if you present it with a load that requires >1.5A input current? If not, then it might be better to go with the BB 750 since you might get lucky and get an IC that can handle slightly higher than 1.5A on the input.
How about the SOB? Same performance characteristics in terms of Iin,max behavior? Any risk of overtaxing that board?
Thank you.
