I use two LT3743 on one board.
When output 6A, the difference of channels is about 300mA.
CH-A is normal, CH-B is low current.
This phenomenon didnot occur on large boards, but this phenomenosn occurs on small boards( 1/4 size)
As a result of the test, it seems to be determined by the stage after the output mosfet.
(It is not a difference in Mosfet device. I tried intalling SWAP, but the result is the same)
