LT3743 : Current Difference between channels.

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)
